So, I'll go months being totally fine, then for NO reason while sitting watching TV all of my nerves fire. Chest and arms feel like they are on fire, constantly feel like I gotta poop, ears ringing (all 100% physical symptoms) and I'm not stressed in the least. Then I go thru the whole, this can't be anxiety something has to be wrong with my brain and/or nerves because it won't stop and I don't know what to do
