So I m an avid smoker, and recently I have been feeling very tired, i ve been getting sick more frequently and these sick periods have been lasting from a week to a couple weeks, my gums are bleeding, im getting a lot of nose bleeds, and I have no energy. I m also only 24 but i have been smoking since I was 13, what should I say to my doctor, and what are the potential things that could be going on?
