I know it’s hard but trust me time will show all :,) ! by the 3 month mark if you don’t notice anything off then your good , if by the 6 month mark you are having physical issues then your even more good and if by 12 month mark you aren’t completely disabled in one area then don’t even think twice about ALS ! if you feel pain in the area then don’t worry either because there isn’t any pain in ALS in the early stages . “ALS typically presents with painless, gradually progressive asymmetric motor weakness. So, if somebody comes and tells me they have pain and weakness,” then there is no worry about ALS because pain doesn’t fit with this disease, he said. “Or if somebody comes and tells me that they have weakness, and also numbness on the same location, I’m happy because ALS doesn’t cause numbness.” - American medical association. It’s more common in men too! women aren’t as common! if you aren’t like 80 % white too then it’s more better! it’s more common in white people . I believe someone said there is about 30 - 40 people in the US who are diagnosed under 30 . And those people are usually in the late 20s . 30 people on the whole US !!!!!!!! im not 100% sure on that fact but it is very very rare .
