So i have this painful bump on my forehead, like a pimple, but its not what is it?? how to get rid of it?

i can feel the pressure theres stuff in there but when i pop it it just gets irritated and it keeps coming back! got some cream from my docotr (antibiotic or medicated or whatever) but it didnt work! (because it keeps coming back!!) HELP its painful, looks disturbing and it wont go away!!!!!!!!|||if you have medicine from the Dr. follow their instructions and go back if you have to so you can get checked out again.|||prob. a cyst|||I had something like that once and it turned out to be excema. Be careful, don%26#039;t pick at it or try to %26quot;pop%26quot; it. I have a small scar becasuse I could not leave it alone!
