Hello, I have a rash in different locations. The locations of the rash is on my legs and one under my left armpit. The rash is bright red, itchy, painful with a white head. Saturday July 5, 2014, I went fishing in the mountains. I got bitten buy nats a few times on my arm. Sunday morning when I woke up, I noticed I had a tick (not engorged) on my left collar bone. I removed the tick (with head still attached to its body). Looked like a male Lone star tick. Around where I found the tick there still is not a mark or anything. I did not notice the rash till late Sunday night. The rash sites started to itch more and started to be painful. Tuesday July 8, 2014, I noticed a whitehead in each rash location. Today the whiteheads are getting larger. Do you have any idea what it could be?
