Been to a doctor a few times about this, weve gone through topical creams, steriods, however no matter what they come back.
They are located in the upper thigh region close to the groin. They are not chaffing.
I've had these since i was about 18, i am now 31. They get to the point that they are so painful i can not walk, i generally get one big (massive) one every month and lots of smaller ones during the month, see the attached pic.
