Leg tumors

Dear all,

I have problem with my leg. For already 5 years I feel unpleasant pain in my leg (similar to small electricity shocks or feeling somebody spelt hot water). Through time something starts growing inside (soft tissue) and slowly my leg started to be without sensation, it is getting numb. This rising tissue under my skin (under quadriceps femoris) is still growing (now it looks like a small bump) and from time to time I experienced unpleasant pain (already described), especially after long walks. I should mention that my leg is strong and I even go to gym doing exercise even though I am sure this pain is not a result of gym injury or any other injury. I blame my self for being lazy but before going to doctor I would like to ask you for advice. What kind of examanation i should ask for?

Thank you very much!

Given the data you provided (unpleasant pain in leg for five years, presence of small bump under the skin that keeps growing) you might have experienced a tumor in the leg.

One of the most common symptoms that are associated with tumors comes from their growing and putting pressure on the surrounding tissues. In your particular case, the tumor might have likely put pressure on the nerves in the leg. The nerves that are responsible for the muscles are located very deep in the leg, beneath the muscles and close to the bone. That is why the movement of the leg is not affected at all. But the sensory nerves are located beneath the skin and that is why you feel strange sensations (unpleasant pain, like someone pouring hot water, tingling, and numbness). These sensations are called paresthesia (meaning sensations without apparent physical cause). If the condition that puts pressure on the nerve is not treated, then it might permanently damage the nerve, by not feeling at all in the affected area all the time.

The true nature of the tumor (benign or malignant) cannot be determined without taking it out and examining it or at least with a biopsy (taking a part of the tumor with a needle).

You might want to visit a plastic surgeon or a neurosurgeon for a physical examination and removal of the tumor. Given the fact that you have had the tumor for five years it is not likely that it is malignant, but it cannot be determined for sure. However, what is important for you is not to waste your time and to visit a doctor for examination and treatment.
