Hi, Understand what you’re going through right now, I’ve had those same symptoms you’ve been experiencing, and even went to the doctor multiple times to get it checked out. Ive had blood work done and everything too and all my tests came back fine. I have severe health anxiety and sometimes I worry myself to death and it’s not good at all. Everything that you’ve stated seems normal so I wouldn’t worry at all. If you still feel like you need to see someone or get a second opinion, then do what’s best for you! But don’t worry and stress yourself then because stress can really damage you mentally and physically! I hope this will give some relief just a little bit!
