Did you ever have chicken pox your entire life? If yes possibility you could have shingles. Which causes red sores and causes you pain. So if anything I would get tested for shingles.
Are you having these bumps anywhere else on your body? Are they draining?
For your bumps, I'd suggest reading at the following sites - doctor yourself by Andrew Saul, mark's daily apple, underground wellness. For your anxiety - some of the previous mentioned sites and look online for The Mood Cure by Julia Ross, which will have some info and you may decide to buy the book. I hope you decide to support your health, instead of just covering symptoms (I know this is the conventional and accepted way but it's not getting to the root cause of the problem you have). best wishes for you
