I have been really itchy in my inner thigh area recently, especially after i sweat. sometimes i will itch a little to hard. the area also no longer grows hair since after my laser HPV removal surgery. Its slippery and raw like. However, at the bottom, there are some small bumps and a small looking cut on the other side. What is the difference between a bump and a blister? The last time I had sex was about three months ago. Could this be herpes?
