Hey man I think it's probably a mixture of your back/nerve hurting and severe case of anxiety.
A few years back I randomly passed out and they kinda explained why it happened, but I didn't fully understand it and ever since then I get this pain on my side and chest. So much so that I had them do like full diagnostics to make sure theres nothing wrong with me.
To this day it comes and goes, but lately it's always there, and I can't help but shake the feeling that something is up and wrong with me.
I had an hour drive home yesterday and about 3 minutes in I had a crazy feeling come over me like I was gonna pass out and my side started hurting, but after a while I think I just convinced myself it's anxiety and made it home.
And yet today I wake up and the pain is back. I also haven't been to the doctor in like 2 years so I should probably just go and get like a full checkup but I'm scared of just wasting my time when it's probably just anxiety issues. But idk.
All of this is to say that I think anxiety can have a pretty crazy effect on you.
Yeah I know it. The crazy part is how I start thinking about it and everything starts slowly getting worse. I'll be like well at least my arm isn't hurting... then a few minutes later sure enough, my arm starts hurting.
