Skin problems

I have been struggling off and one w/ flareups that never fully go away just get worse or stay moderate. My face is always red and painful especially tzone, cystic acne and surface lesions on face that are not large resembles acne but is not. They often burst open on own and the drainage is always yellow. I had broken my tailbone as a child so the soreness I experienced in my tailbone i thought was from prior injury but it often becomes really sore and develops cellulitis the area becomes hard/firm/red, never develops a head but eventually burst and drainage is bloody and yellow as well. The bartholian cyst comes snd goes bilaterally but never at same time . It becomes so painful and round until it burst as well drainage is yellow and bloody. Even after pain and swelling subsides there is always a lesion remaining. I have been on countless medications ations- antibiotics topical, oral, and iv. They help at first but then returns. I am at my wits end. Im not obese and shower daily.

No change
