My roommate has had a reddish 'rash' on his neck, upper shoulders and upper chest area for several months now. It's not anywhere else on his body. There are also small red bumps.
It burns after he takes a shower, and at times it itches. Also, whenever he's in any type of heat, it burns and/or turns redder (hot shower, outside, etc.)
We're not sure if it "might" be an allergy, or exposure to some type of food or work surroundings, or some other explanation.
He also had some dental work done, and thought it "might" be the infection from his tooth, or the novacaine that was used (several months ago).
He noticed that is got better when he was off work for over a week, and the last 2 days, it's gotten worse.
Any insight would be helpful.
