Thigh nerve issue (meralgia paresthetica)
Meralgia paresthetica is a nerve condition that causes an area of skin over the upper outer thigh to feel numb, tingly, or painful. This is caused by compression of a nerve known as the lateral cutaneous nerve of the thigh as it passes underneath a tough fibrous ligament known as the inguinal ligament.
You should visit your primary care physician to confirm the diagnosis and discuss treatment options. Generally, this condition is treated with rest, physical therapy, pain medication, and occasionally corticosteroid injections.
Rarity: Rare
Top Symptoms: pain in the outside of the hip, pain in one thigh, thigh numbness, tingling upper leg, hip numbness
Symptoms that never occur with thigh nerve issue (meralgia paresthetica): new headache, swollen hip, swollen hips, swelling of one hip, leg swelling, weakness of both legs, leg weakness
Urgency: Primary care doctor
Thigh bone infection (osteomyelitis)
Osteomyelitis of the thigh, or thigh bone infection, is a bacterial or fungal infection of the thigh bone, typically caused by Staph Aureus (40-50% of the time). It is difficult to diagnose as the infection can come from a break in the skin at the area or anywhere else in the body that spreads by blood.
You should seek immediate medical care at an ER, where diagnosis of osteomyelitis can be established through x-rays and culturing fluids. Treatment involves antibiotics and removing the infected tissue (by surgery).
Rarity: Rare
Top Symptoms: moderate fever, constant upper leg pain, spontaneous thigh pain, painful surgical site, warm red upper leg swelling
Symptoms that always occur with thigh bone infection (osteomyelitis): spontaneous thigh pain, constant upper leg pain
Urgency: Hospital emergency room
Spinal stenosis
The spine, or backbone, protects the spinal cord and allows people to stand and bend. Spinal stenosis causes narrowing in the spine. The narrowing puts pressure on nerves and the spinal cord and can cause pain.
Next steps including visiting a primary care physician. For this condition, a physician might suggest further investigation including imaging of the spine. Treatments may include medications, physical therapy, or braces. For severe cases, surgery is sometimes recommended.
Rarity: Common
Top Symptoms: lower back pain, back pain that shoots down the leg, back pain that shoots to the butt, difficulty walking, thigh pain
Urgency: Primary care doctor
Repetitive strain injury of the quadriceps
Repetitive strain injury of the upper leg is caused by consistent repetitive use.
You do not need treatment, just rest from your overuse. Wearing a brace and physical therapy might be helpful.
Rarity: Uncommon
Top Symptoms: upper leg numbness, thigh weakness, thigh pain from overuse
Symptoms that always occur with repetitive strain injury of the quadriceps: thigh pain from overuse
Symptoms that never occur with repetitive strain injury of the quadriceps: upper leg injury, severe upper leg pain
Urgency: Self-treatment
Pulmonary embolism
An embolus is a blood clot that forms in the bloodstream, breaks loose, and is carried by the blood to become lodged elsewhere in the circulatory system. If this clot (embolus) blocks part of the bloodstream in the lungs (pulmonary system,) this condition is called pulmonary embolism.
It is most often caused by blood clots in the deep veins of the legs, which can form after long periods of inactivity or bedrest.
Other risk factors include smoking, obesity, and female hormone replacement therapy.
Symptoms include sudden difficulty breathing; chest pain; coughing, sometimes with blood; anxiety; lightheadedness; and fast, irregular heartbeat.
Pulmonary embolism is a life-threatening medical emergency, because it causes high blood pressure in the pulmonary arteries and lack of oxygen in the blood. Take the patient to the emergency room or call 9-1-1.
Diagnosis is made through patient history, physical examination, blood tests, and chest x-ray.
Treatment involves anticoagulants, or blood thinners; "clot-busting" medications; and surgery to implant a filter to help prevent clots from traveling through the bloodstream.
Patellofemoral pain syndrome
Patellofemoral pain syndrome (PFPS) is also called runner's knee, jumper's knee, anterior knee pain, chondromalacia patella, and patellofemoral joint syndrome.
Overuse through training for sports is a common cause, especially if there is a misalignment in the knee joint or a previous knee injury. This wears away the cartilage beneath the kneecap and causes pain on exercising.
It is most common in females and in young adults who are active in sports, but can affect anyone.
Symptoms include dull pain at the front of the knee and around the kneecap (patella) while running, squatting, or climbing stairs, or after prolonged sitting with knees bent.
Diagnosis is made through physical examination and through x-rays, CT scan, and/or MRI.
Treatment most often involves rest; over-the-counter pain relievers; low-impact exercise such as swimming or bicycling; physical therapy to strengthen and stabilize the knee; and orthotics (shoe inserts) to help correct a misaligned stride.
Surgery is needed only for severe cases, and is done through arthroscopy to remove any fragments of damaged cartilage.
Rarity: Common
Top Symptoms: knee pain, pain in one knee, knee pain that gets worse when going up stairs, dull, achy knee pain, knee pain that gets worse when squatting
Symptoms that always occur with patellofemoral pain syndrome: knee pain
Urgency: Primary care doctor
Greater trochanteric pain syndrome
Greater trochanteric pain syndrome, also called trochanteric bursitis or GTPS, is an inflammation of the bursa of the greater trochanter.
Bursae are the small "cushions" between tendons, bones, and muscles. The greater trochanter is the larger of two bony knobs at the top of the thigh bone. Overuse, trauma, or infection can cause inflamed and irritated bursae around the greater trochanter.
Most susceptible are individuals with low back pain, osteoarthritis, and obesity.
Symptoms include chronic, persistent pain on the outside of the hip that radiates down the outside of the leg, sometimes to the knee.
The symptoms are similar to other conditions such as degenerative joint disease, and so a medical provider should be seen for an accurate diagnosis.
Diagnosis is made through physical examination and observation of simple movements.
Treatment largely involves managing the symptoms through weight loss, physical therapy, and over-the-counter nonsteroidal anti-inflammatory drugs. In some cases, corticosteroid injections into the hip work well to relieve pain, and surgery can sometimes help.
Femoral stress fracture
Femoral stress fracture means there is a break in the femur, or thighbone. The femur is the largest and strongest bone in the body and is important for bearing weight. A femoral stress fracture usually occurs in the top of the bone where it connects to the pelvis.
Stress fractures happen from overuse and/or from weakness in the bone from disease, rather than from trauma. Those in heavy physical training, such as athletes and military trainees, are vulnerable to femoral stress fracture. But anyone suffering from malnutrition or osteoporosis is vulnerable to a stress fracture, even with ordinary activities of daily living.
Symptoms include pain deep in the thigh or groin, especially during exercise. The pain may have started gradually instead of being sudden, as with a traumatic injury. The condition might be thought to be a simple strain.
Diagnosis is made through physical examination, with simple tests such as hopping on the painful leg, and imaging.
Treatment involves rest; improved nutrition; study of proper training and striding techniques; and sometimes surgery.
Rarity: Common
Top Symptoms: dull, achy hip pain, pain in one thigh, thigh pain, spontaneous hip pain
Urgency: Primary care doctor
Deep vein thrombosis
A deep vein thrombosis (DVT) occurs when a blood clot forms in a vein deep in the body, usually in the lower leg or thigh. DVT can cause swelling, pain, and redness in the affected leg. Some of the risk factors for developing DVT include obesity, pregnancy, cancer, surgery, and previous history of blood clots.
You should consider calling your primary care or urgent care provider. Deep vein thrombosis can be evaluated with a review of your symptoms, a physical exam, and an ultrasound. A blood test may also be performed. Once diagnosed, DVT can be treated with blood-thinning medication, which is usually taken for three months.
Rarity: Uncommon
Top Symptoms: fever, thigh pain, upper leg swelling, calf pain, butt pain
Urgency: Hospital emergency room
Compartment syndrome
Acute compartment syndrome describes the damage done to certain muscle groups of the arms or legs after a traumatic injury.
All of the long muscles are bundled into sections – "compartments" – by the white sheets of strong, tough connective tissue called fascia. If something interferes with circulation so that blood flow is trapped within the compartment, pressure rises because the fascia cannot stretch. This causes serious damage to the muscles and other tissues within the compartment.
Acute compartment syndrome is caused by a broken bone; a crush injury; burns, due to scarred and tightened skin; and bandages or casts applied before an injury has stopped swelling.
Symptoms can rapidly intensify. They include severe pain and tightness in the muscle; tingling or burning sensation; and sometimes numbness and weakness.
Acute compartment syndrome is a medical emergency which can result in loss of the limb. Take the patient to the emergency room or call 9-1-1.
Diagnosis is made through patient history and physical examination.
Treatment involves hospitalization for emergency surgery and, in some cases, skin graft.
Rarity: Rare
Top Symptoms: arm numbness, hand numbness, foot numbness, pain in one leg, thigh numbness
Urgency: Hospital emergency room
When to see a doctor for thigh pain
In some cases, even though emergency treatment isn't necessary, you should seek medical evaluation and treatment for your thigh pain symptoms. You may undergo a physical exam, imaging, and/or blood tests that will help diagnose the cause and guide treatment. Make an appointment with your medical provider if:
- You have chronic thigh pain that has become more severe over time
- The pain is accompanied by numbness and/or tingling
- The pain is particularly bad at night
- You were previously diagnosed with a chronic medical condition like liver or kidney disease
At-home treatments for thigh pain
For more mild cases of thigh pain, you can try the following remedies at home.
- Heat or ice: Heating or ice packs will improve many causes of thigh pain.
- RICE: If the pain started after an acute injury, try RICE treatment. This means resting and icing the muscle, as well as applying compression (such as with an ace bandage) and elevating the leg to prevent swelling.
- Pain medications: Ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) can help, particularly if the pain started after an injury. Do not take the medication for more than a week without seeing a medical provider.
- To address nightly pain: If the pain is worst at night, avoid substances like caffeine, alcohol, and nicotine. Improving your sleep habits, such as by going to sleep at the same time every night and making sure the room is dark, may also help.
- Drinking plenty of water may help relieve crampy thigh pain
