hello my name is Mike, I was bitten on my elbow back in 2010 here in kuwait by something. I had an MRI done because the infected ares was hot, needless to say I was treated & the infection went away. To this day I have had hard heated bumps appear on my forearm, neck, & the back of my head. Recently I had one appear on my left chest, all go away with an antibiotic, but before they do, I can squeeze the same yellowish pus out of them all. Can you help?
