Dermatology/Painful leg skin


Hi Michael,

I have this weird problem that I'm not sure what medical field it fits into. I'm 67 and in pretty good health. My circulation is good and internal organs working well.

Yesterday my left leg began hurting from the knee up to the groin. It's like the skin has turned inside out and the nerves are ultra sensitive. A bit like a sunburn sensation. The skin isn't hot at all and there's no redness or rash. Today the right leg has done the same thing. When I walk, the material of my jeans rubbing against the skin is quite painful.

Do you have any idea what could be causing this? I suspect it's temporary but wonder if there's anything I can do about it.

Many thanks,

Paresthesia refers to a burning or prickling sensation that is usually felt in the hands, arms, legs, or feet, but can also occur in other parts of the body. The sensation, which happens without warning, is usually painless and described as tingling or numbness, skin crawling, or itching or painful.

Most people have experienced temporary paresthesia -- a feeling of "pins and needles" -- at some time in their lives when they have sat with legs crossed for too long, or fallen asleep with an arm crooked under their head. It happens when sustained pressure is placed on a nerve. The feeling quickly goes away once the pressure is relieved.

Chronic paresthesia is often a symptom of an underlying neurological disease or traumatic nerve damage. Paresthesia can be caused by disorders affecting the central nervous system, such as stroke and transient ischemic attacks (mini-strokes), multiple sclerosis, transverse myelitis, and encephalitis. A tumor or vascular lesion pressed up against the brain or spinal cord can also cause paresthesia. Nerve entrapment syndromes, such as carpal tunnel syndrome, can damage peripheral nerves and cause paresthesia accompanied by pain. Diagnostic evaluation is based on determining the underlying condition causing the paresthetic sensations. An individual's medical history, physical examination, and laboratory tests are essential for the diagnosis. Physicians may order additional tests depending on the suspected cause of the paresthesia.
