I am not sure what to do?... I think I may have tonsillitis...I have been on & off of antibiotics since December 2015 & I have had two extreme cycles of sore throat, swollen lymph nodes, heavy chest congestion, sinus problems, extreme fatigue, etc.....the swollen lymph nodes & blistered throat never completely heals. I am also tired all the time. What should I do??? I would hate to go through round 3, but there is nothing I can do to get better...please help!!!
