Hello, doctor. I have had a lump in my left armpit since late November. I went to the doctor four times and each time I was given an injection and some antibiotics as well as painkillers for the pain that was in my left arm and upper back left side. They gave me amoxylin, amoxycilin, ranclav 625 and the last time it was just an injection and 8trek drawing ointment as the doctor thought it might be a boil. None of the above worked and when I used the drawing ointment another lump appeared just below the first one and surprisingly the first one started to shrink. This one felt very painful and I started applying garlic and warm compresses. Now it s not so painful and feels softer to the touch but today I have this excruciating pain down my left arm and upper back left side and I m very worried, please help. I forgot to mention, the first time I used antibiotics it shrank bt started getting bigger again, that is the first lump
