having muscle twitches (and sometimes crawling feeling) in both legs, claves, thighs. very random. i notice in my arms sometimes too. been going on for 3 weeks. i noticed after adding running back into my routine.(ive since taken running back out) Googled muscle twitching. The first thing that comes up is ALS. ive been in a panic ever sense and basically have convinced myself i have it. I went to my Dr. he said twitching benign 99% of the time, but wouldnt completly rule out something more sever (like ALS) this did not help. He said he didnt feel the need for me to see a neurologist, but could if i wanted to. The next appt is two months away. Ive read in some cases muscle twitching can be the first sign. im going crazy. does anyone have similar symptoms, or can relate?
