I have pain deeper in the thigh which is actually a pinched nerve from my lower back which is relieved by chiropractic. My skin is also ultra sensitive, sometimes just from wearing jeans that rub the wrong way, and I am right handed so my whole right side is a bit bigger and the right pant leg can chafe when the left does not. Sometimes just from sleeping on the side and having my underwear pull against my groin. I always wear my underwear inside out to have the seams not against my skin. I would wait another few days but then talk to a doctor.
