then my legs suddenly move
i think ive had this ever since i started lifting weights
and sometimes after school i have really bad frequent headaches..but i havent had some in a few weeks

Answer 1

There are different reasons, but I suspect a trapped nerve could be one. Are you on any medication as some meds can cause this?

However, you should really see a doctor as a small possibility is a form of epilepsy.

Answer 2

Worst case scenario--one of your vertebrae has slightly misaligned and it is pinching a nerve. BUT since you feel tingling in both your arms and legs, this is very unlikely. It would mean you have a slipped cervical AND also lumbar vertebrae. If this was the case, you would always be in pain, and always have a tingling sensation all the way down you arms and legs.



So just relax, when I was working out and taking supplements I always had some sort of twitching here and there. Sometimes it would be in my triceps, sometimes my thighs. It would twitch for a few seconds at a time, 2-4 times a day. I imagined it was some air bubbles or something, the way it felt.

Answer 3

Yeah my biceps and forearms started acting strange after weights too. You may want to see a doctor but I am trying more water, bananas, and gatorade because after talking to the physicla trainer I think that I might have low potassium. See below as it sounds like your symptoms



Tetany



In tetany, all of the nerve cells in the body are activated, which then stimulate the muscles. This reaction causes spasms or cramps throughout the body. The name tetany is derived from the effect of the tetanus toxin on the nerves. However, the name is now commonly applied to muscle cramping from other conditions, such as low blood levels of calcium and magnesium. Low calcium and low magnesium, which increase the activity of nerve tissue non-specifically, also can produce tetanic cramps. Often, such cramps are accompanied by evidence of hyperactivity of other nerve functions in addition to muscle stimulation. For instance, low blood calcium not only causes spasm of the muscles of the hands and wrists, but it can also cause a sensation of numbness and tingling around the mouth and other areas.



Sometimes, tetanic cramps are indistinguishable from true cramps. The accompanying changes of sensation or other nerve functions that occurs with tetany may not be apparent because the cramp pain is masking or distracting from it.

Answer 4

Restless leg syndrome? I have that, sometimes in my arms too. Maybe a pinched nerve from lifting? You are probably too old to have started developing tourettes, so if it continues, see a doctor.

Answer 5

Why haven't you seen a doctor for a medical evaluation?
