Inner thigh rash

I have a patch of red bumps on each of my inner thighs, near the fold of the groin (not actually on groin). I noticed this close to a week ago. It's fairly itchy, raised, and a red/peach color. I've read things online that say it might be because of sweating or tight clothing. I haven't been sweating more than normal, but I did recently buy some boxer briefs that were a bit too tight on the inner thigh area. Could that be what started the strange rash?
Even if that is what caused it, what should I do to treat it? Will it heal in time, is there an over-the-counter cream I could use, or should I just go see a dermatologist?
