I think health anxiety must be something a lot of us have in early sobriety. I see people posting various "issues" they are having after first stopping and issues on into post acute withdrawal. I'm sitting at five months. I could swear up and down that I have a bad heart. However every test I get comes back normal. Anxiety can really run and ruin a person's life.
I see lots of good advice on the boards about getting a handle on paws and anxiety. Time is one of the big factors. The farther we get away from that last drink the better its supposed to get. Just keep plugging away and it'll get better. Hopefully you find your light at the end of the tunnel.
