Has anyone ever had this? What did you experience?

I’m fearing I might have it or getting it?

I got strep nearly two weeks ago. Treated it with amoxicillin that I already had. It was maybe a year old. Anyway, I knew it was strep. I’ve had it before and I had the classic symptoms especially the pus and marks on the tonsils. Anyway. I’m positive it was. I would be surprised if it wasn’t. Anyway, I started to feel better soon after except a lingering sore throat. And then just a couple of night ago I started to get a scratchy throat and feeling the need to cough. Now I’m achy and sore. I have headaches. Very weak. Chest feels extremely tight and I feel out of breathe.

I don’t want to jump the gun but should I see a Dr like tomorrow?
