Hello, I've been feeling out of it since January, it started off with some type of weird feeling in my head, something like brain fog, then my throat was feeling like I have something stuck in it now just the other day as I was laying down & a shocking/tingling feel went thru my chest,l. I've had blood work done, a cat scan, ekg & xrays and everything came back OK. . .I just want answers because I'm stressed out not knowing what's wrong with me. . .what can it be?????
