Hi , I m concerned I may have a serious health issue , maybe even cancer. For a while now I ve been getting reoccurring puss filled bumps under my arm pits that smell horrible when popped. At first I thought it was the razor I was using to shave. So I changed my razor brand and started to use more aloe to soothe after I shaved. However the bumps still appeared. I then thought maybe it was the deodorant I was using so I changed that as well. Again the bumps appeared in the same spots as usual. I thought maybe it s ingrown hair due to shaving? Maybe it s an abscess or a cyst ?that may need an antibiotic, mersa? Or the worse case scenario cancer. So do you have any ideas or suggestions as to what it is and what I should do ....
