I have this too large to be a pimple red thing right above my collar bone. it looks like it has like a black thing inside the middle too. when I got it I got really dizzy, enough where I had to sit down or lean on something to get rid of the sudden dizziness. I am 14 and should I be concerned? it stings and some how feels like a bruise and is very hot.
Dear patient You have got infection of skin area around collar bone. Are you having fever? If yes then its sign of infection. Get your blood tested for total blood counts and differential blood counts.  Increased leukocyte count is sign of infection.  Start tab diclofenac 50\u00a0mg twice a day for pain relief plus tab augmenting 625 mg thrice a day for 7 days. This will relieve pain and infection.  All the best.
