Great question! I would love to know the answer to that also. I have the same thing. It comes and goes. Does it feel like water running down your leg? Mine is by my vericose vein. I wonder if it has something to do with that?
wow, my husband occasionally complains of the same sensation! I just thought he was being silly....he is reasonably healthy but used to smoke quit about a year ago, no varicous veins that I know off, not a great exerciser but taken up running recently and hasn;t complained about it for a while.
Iw ould be interested to see if this has a medical link...
That is nerve sensation. It can also feel like ants crawling under your skin. When I had a broken back and lost use of my left leg and quad muscle, the first nerve feeling that returned felt like ants under my skin, then like little worms crawling, then like water running. It's all related to nerve regernation.
Have you talked to a Dr.? I agree that this could be from a nerve yet there are so many things that could cause this....It took me several years to find out what was going on...Although, mine is linked to auto-immune diseases, I feel that everyone should check with their Dr. This could also be a circulation problem. It can be linked with diabetes or so many other disorders...I was also checked for MS with this along with other symptoms before discovering the underlying cause. I don't mean to put a scare out there but if you don't know what's causing a weird symptom...By all means ask someone who has knowledge of your health history.
I've had the same feeling on and off my whole life. I never thought much about it--I guess I thought everyone had it. I believe it's a nerve sensation and nothing more. Next time you go to your doctor you might mention it and see what he/she thinks. In my opinion, if it was something needing immediate attention you'd have symptoms such as weakness, fatigue, lightheadedness, etc. Of course, if you have a history or heart disease or stroke, you should contact your doctor immediately. But what you describe sounds fairly benign to me. Do a search and see what you can find.
