ask: What is this twitching in my leg? Help!

By Anonymous

Yesterday afternoon, I started getting a weird twitching/pulsating in my right thigh, just above the knee. It doesn't hurt atall and feels very much like an eye twitch I got years ago.
The thing is, I STILL have it a day later. I though it would disappear in the night but it didn't!
Just before it started, I had walked up some VERY steep streets and down them again. I work out a lot though. The only difference was that these streets were particularly steep and a bit scary to a person afraid of heights.

I'm sure there is nothing I can do but wait it out but I was wondering if anyone knows what this is and how to stop it? It creeps me out more than anything as I have no pain and tend to forget about it when I am busy rushing around but then feel it again when I relax.
Please help!

Hi Anonymous-

I wrote an article on this recently: http://www.empowher.com/news/herarticle/2010/03/30/muscle-twitching

In your case, since you don't mention any other muscles twitching or any cramping, my guess is the twitch is directly related to the hill climbing. You may have fatigued that particular muscle and irritated the motor nerve a bit. It is irritating, but it will most likely go away on its own.

If you had multiple twitchy spots or cramping, I would say you might be dehydrated or have an electrolyte imbalance. But this is likely fatigue and motor nerve irritation. Sometimes you can distract your nerve/brain by icing the area briefly. Be sure you are hydrated and eating a balanced diet. If the twitching goes on for more than a week, you should check in with a health care provider just to be sure nothing else is going on.

These twitches are annoying, but very common. I hope it resolves soon.
