Ive had itchy, painful bumps on my butt cheeks for over 10 years. They come and go, but now theyre harder to drain. They also sometimes appear on my inner thighs and sides. Any advice on what this could be?

Based on your description, it sounds like you may be experiencing recurrent episodes of boils or abscesses. These are usually caused by bacterial infections of the hair follicles. To help treat and prevent these bumps, I recommend practicing good hygiene by keeping the affected areas clean and dry. You can also apply warm compresses to the bumps to help them come to a head and drain. Additionally, you may benefit from using an over-the-counter antibiotic ointment like Neosporin to help prevent infection.
