I have some questions about ALS. I am 30 years old and started experiencing a strange tingly type feeling in my left arm about 1 month ago, particularly in my thumb. I have not particularly noticed any weakness, although I am now noticing my left arm seems to tire more easily especially with repetitive activity. I am the mother of two small children and I don't notice any weakness in picking them up or anything. I have occasional mild twitches - more like one twitch and then nothing for awhile. I started going to a chiropractor who believes I have a pinched nerve in my neck. The weird thing is that some days it feels much better and I hardly notice it, then the next day it will feel very strange again. I find myself wondering if it is actual weakness in my arm or just a weird feeling. Does this sound like the beginning of ALS? I have gotten so scared about it that I think I may be imagining more symptoms than I actually have. I would appreciate any input.
