Hello, I have a fairly large bump on my right side it's about 3 inches to my armpit. The bump is hard and very painful, looks bruised, and is light pink in color.

Last year I had a lot of bumps like this on my thighs, and also on the sides of my upper body, the doctor gave me "antibiotics" saying that the blood is infected some bacteria that is making these. He told me to take it for 6 months, but the pills made me sick, I took them for 3 months. He also said this is a sweat problem area. where bumps like that will form because its closed up all the time and getting heated.

Please give me more information if there is any about this. If you need a picture I will take one.
