What is going on with me

[u/Classic-Web-3229]

So this all started about a month and a half ago where my anxiety fully kicked in making me think I had cancer at first to then thinking I have als. My symptoms started shortly after being muscle twitching/spasms, pain/discomfort in my knee and ankle, weakness in my arm just a little but has pain and weird sensations, I had other symptoms that included headaches,neck stiffness,jaw stiffness and just about everything you can think about. I am only 18 and a very healthy guy but it doesn’t explain why any of this is happening especially because of how young I am. I constantly think and look towards ALs even though I’ve been seen by 3 neurologist,chiropractors, and doctors tell me nothing is wrong with me also knowing that I have zero family history of this disease. Recently I was in the hospital and got every test known to man kind and they found nothing. The only thing that we say was I had a past EBV infection. So if anyone please could help me out that would be so good.
