Cold this be ALS

[edubona]

Hello, my name is Eduardo, I am 22 years old and since May 18th I have been experiencing strange sensations, it all started with a sharp pain in the left calf, then the burning pain spread to the whole leg, including the buttocks, and so on it was left. From the 22nd I felt difficulty swallowing as if my throat was closing or with a lump, in addition to dry mouth and accumulation of saliva. And today I'm feeling a burning pain all over my body, including in my left shoulder, in addition to the beginning of weakness (I can walk on my toes). But what intrigues me most is the difficulty in swallowing and also a certain wheezing in the chest and throat. I would like to know if it could be a case of ALS?

I have pain in the back of my neck and am also having difficulty sneezing would this indicate a bulbar onset?
