Hi, about two weeks ago I started feeling a small Lump under my left armpit.  Over the coarse of a few days it started getting Wider.  To a point it became reddish and painful.  Yesterday I noticed a white head similar To a pimple in the middle of it.  When I squeezed it pus and blood came out of it.  It would stop after a bit and then it would fill with puss again.  I feel it has gotten a bit smaller now and less painful .  Tonight when I examined it I noticed I have about 9-10 small red spots all along side my armpit, any suggestions as to what this could be??  I have type 2 diabetes and Im overweight
This is hi Chat Doctor.  It is infection of the sweat glands in the armpit. Go to a general surgeon, he will clean it and take a sample for pus culture and sensitivity. Antibiotics will be prescribed according to culture report.
