What Does A Sore Lump On The Head Along With Red Spots And Areas On The Forehead Indicate?

I recently noticed a lump in the top left of my head. It was extremely sore to touch...and now a week later is approx the size of pea...way smaller, less painful. At that same time I had 2 red spots appear on my forehead that were painful and a small red area at the left temple (on hairline), also painful. Also, pain behind my left eye, more toward the outer edge, in front of my left ear (now gone), and scalp in the left area is very sensitive to touch and actually hurts. I am perplexed. I have never experienced symptoms like this before
