i have been having some pretty bad side effects from vaping. constant sinus issues (blood and all). and a very itchy scratchy infected throat and esophagus. went to doctor said it was a sinus infection and my lymphnodes are swollen. didnt tell him about vaping, figured he wouldnt know if it was causing it or he would automatically say thats whats causing it. i have been taking antibiotics and a steriod to reduce inflamation. i am pretty sure its vaping causing this. if i dont vape i dont get the issue in my esophaguss but if i do half hour in i feel my esophagus getting inflamed and itchy. it also looks like i am bleeding from my esophagus because my stool is pretty black which indicates internal bleeding somewhere in the esophagus or a ulcer and i dont have a ulcer. so i vaped a little today and instantly my esophagus started to hurt. looks like i am going to have to put a halt on vaping for awhile until i am cleared up. could be a coinsedence that i got sick the same time i started vaping or its vaping causing it. going to wait until its all gone and try to vape again and see if this issue returns. if it does its going to mean quiting cold turkey. will keep you all informed.
