Thigh pain

I am an office worker who sits at a desk, and over the past few months, I have been experiencing occasional unexplained pain in my left thigh while sitting without exertion.
The pain is located approximately in the mid-thigh area, not at the joint.
When it occurs, it can be quite intense, but it subsides after a few seconds or minutes.
Typically, it happens every few days or once a week, mostly during the daytime.
A month ago, I visited an orthopedic clinic and had an X-ray taken, but the doctor said there were no abnormalities and advised me to rest at home.
However, the pain still recurs every few days.
I do not have a regular exercise routine, except for climbing 11 flights of stairs to my office every morning (a habit I have maintained for nearly a year), but it doesn't feel like muscle pain.
Could you please advise me on which specialty I should see at the hospital? What could be the possible issue?

Hello Mr.
Amin: Leg pain is one of the most common symptoms.
The legs bear the body's weight daily, and standing for too long or walking excessively can lead to leg pain, weakness, and even numbness.
Additionally, intense exercise, inappropriate footwear, and sprains can also cause leg pain.
It is also important to remember that underlying medical conditions can exacerbate leg pain, weakness, and numbness.

Analyzing the symptoms, lower back pain accompanied by radiating leg pain and weakness may indicate sciatica.
Hyperuricemia, knee joint swelling, pain, and weakness while walking may suggest gout.
Prolonged elevated blood sugar levels leading to cramps and weakness during walking could indicate peripheral circulation issues related to diabetes.
If there is hypertension, weakness and numbness in the lower limbs requiring assistance while walking may be indicative of primary hyperaldosteronism.
In cases of heart disease, generalized edema, long-term use of diuretics, and accompanying leg weakness and numbness may suggest hypokalemia.

Management includes rest; avoid unnecessary movement to prevent falls and injuries, and do not stand for prolonged periods.
If you have any questions, feel free to visit the outpatient clinic for discussion.
Thank you!

More Info

It sounds like you're experiencing intermittent thigh pain that is quite bothersome, especially since it occurs without any apparent trigger and can be quite intense. Given your description, there are several potential causes for this type of pain, and understanding them can help guide you on when to seek further medical advice.

First, it's important to consider the nature of the pain. Since you mentioned that the pain is located in the mid-thigh and not in the joint area, it could be related to several musculoskeletal issues. One possibility is muscle strain or overuse, even if you feel you are not exercising regularly. Climbing stairs daily could contribute to muscle fatigue or strain, particularly if your body is not accustomed to that level of activity.
Another potential cause could be nerve-related issues, such as meralgia paresthetica, which occurs when the lateral femoral cutaneous nerve is compressed. This condition can cause pain, tingling, or numbness in the outer thigh and can be exacerbated by prolonged sitting or tight clothing.
Additionally, you might want to consider vascular issues, such as deep vein thrombosis (DVT), especially if you have risk factors like prolonged periods of sitting, recent travel, or a history of clotting disorders. DVT can cause sudden pain and swelling in the leg and is a serious condition that requires immediate medical attention.

Since your X-ray did not show any abnormalities, it might be beneficial to consult with a specialist who can evaluate your symptoms more thoroughly. Given the nature of your pain, I would recommend seeing a physical medicine and rehabilitation (PM&R) specialist, also known as a physiatrist. They can assess your pain in the context of your overall physical health and may suggest further imaging studies, such as an MRI, to evaluate soft tissue structures, or nerve conduction studies if a nerve issue is suspected.

In the meantime, consider some self-care measures. Applying heat or cold to the affected area may help alleviate pain. Gentle stretching and strengthening exercises for the thigh muscles could also be beneficial, but it's essential to avoid any movements that exacerbate your pain.
If the pain persists or worsens, or if you experience additional symptoms such as swelling, redness, or warmth in the thigh, it would be prudent to seek medical attention sooner rather than later. Persistent pain should not be ignored, as it could indicate an underlying issue that requires treatment.

In summary, while your initial X-ray did not reveal any significant problems, the intermittent nature of your thigh pain warrants further investigation. Consulting with a PM&R specialist would be a good next step, and in the meantime, consider self-care strategies to manage your discomfort. If any alarming symptoms arise, do not hesitate to seek immediate medical care.
