During my drinking days I had several pains and internal issues that went away after I stopped. I used to have a terrible ache in my lower right abdomen, in my gut. Not sure what that was. I also had bad bowel problems (sorry to bring it up) that resulted in me crapping bile-colored water. Yuck. Also went away. I had psoriasis quite badly on my elbows, knees, back, and thighs. Cold sores that wouldn't heal too. Same story, those went away after I stopped drinking. I bet you will notice a lot of your issues get better - but you must quit drinking totally for that to happen.
I am just sharing my experience. I am in no way qualified to give medical advice - but I thought you would like to hear it. It is strongly suggested (if not a rule) that we NOT give medical advice on this board. I suggest you see your doctor about the issues. Be honest, and I bet you will find, much to your relief, that your new lifestyle will help your cause.
