I am 26 year old male, i have fasciculations in both legs mainly thighs but recentlly spread to left shoulder and biceps and lower legs. I also have bad nerve pain in all parts of both legs which gets worse when i walk and slightly better with rest. My knees felt fine until recently the pain became bad and right side of right knee feels weak, not sure if its just stiff or weakness. What is this?? Is it MS, ALS, or what?? I havent seen anyone with these symptoms here.
