I have horrible twitching as well! it started in my feet then in my calves to! its all the time! i also have it in my stomach, back, neck, buttocks! and what freaking me right out...tongue
its gets worse with anxiety but it will go through times like my tongue now that is pretty constant for a while....i am scared of als
BUT the doctors tell me it is just anxiety related - and if your on this forum you have some anxiety to
one of the most common places to have twitching is actually in your calves!
and what everyone keeps telling me twitching without weakness or atophy is NOT indicative of als!
People have told me to check out BFS (Benign Fasciculation Syndrome) - harmless - pretty much just intense twitching caused by anxiety...many people who have bfs think they have als - which just causes the twitching to get even worse.
you should google bfs and check this out, i think it will help you realize that calf twitching without any other signs is very common and usually just from exercise, stress, anxiety etc.
So try to relax and not think about it (I KNOW how hard this is...people tell me the same all the time) but from what you have said I'm sure you are just a benign twitcher, like me, and this will all pass.
