Razor burn gone wrong??!

I recently started shaving again and I got really bad razor burn right on the thigh/groin crease. One bump got inflamed and I picked at it and then the skin around started peeling. It's now like the size of a dime. I've been putting tea tree oil on it and it's not doing much. The skin around is getting irritated and making the other little bumps worse too. I'm just paranoid it's something other than an excessive skin reaction to irritation? Oddly enough I had a similar little blister reaction on my neck last week and I have another on my leg. not sure if those are related or its just odd timing. EDIT:: It's not itchy at all, it literally feels and looks like when you get a blister or burn. Just the top skin peeled off around the bump
