i have been experiencing muscle spasms constantly every day for the last 4 or 5 months. the spasms included trembling or like a steady beat (such as a heart beat). i have been to the docotor and got my iron, calcium, and b12 checked. everything pretty much came back normal. my b12 level was low so i started receiving the b12 shot that hasn't helped at all.. its like i feel weak sometimes. i cant open pill bottles or open like a 40 ounce beer for example. i really dont know whats going on and it bothers me everyday to see my leg or arm jumping and not know why. is it a such thing as ur muscles depleting away or something? if so, are there any solutions?? what about steroids or something? would that me gain my muscles back? my friends tell me everyday that it seems as if im losing weight but basically im the same weight but i feel and look differently. my neck seems skinner along with my legs and arms so im thinking i have little or no muscles. i weigh about 137 and i asked a friend how much did it look like i weighed and she said 115. i just want to be healthy or at least aware of whats goin on with my body. also, over the summer before the muscles spasms started to occur i had to go to the doctor for a high fever and back pain. really doesnt know if that has anything to do with it but that it would be helpful because the muscle spasms started after that happened. basically im trying to build my muscles back and figure out whats wrong with me. this is a serious matter to me andi hope someone can help me with this problem... thanks :-D
