It is the worse. I've been dealing with one on my labia for over a year. Somethings I wish and should've done: dry area as much as possible and apply a protectant barrier like A&D ointment, bacitrin. What helped alot is after shower, lay with legs apart if possible. At night is a good time to "air out". And keep covered. The best cause is the roll because it's the softest and cause less friction. Take vitamin E, drink cranberry or cherry juice with aloe vera juice. When youre able to air out, you can even apply organic honey. I hope anybody this helps. God bless!

This is a life long condition which is something to keep in mind when taking antibiotics. I was diagnosed with HS at 16 and now I'm 54. I have not taken antibiotics for many years because if I need them for something more severe I don't want antibiotic resistant.
I've taken all kinds of meds, and many different procedures. My groin "exploded" with cysts during my 1st pregnancy. 12+ inner thighs for a beginning.
I take 50mg of zinc and D-3 every day. I have more than one autoimmune but never catch so much as a cold or worse.
I pay attention to the design of my underwear, if any, as much cotton as possible but watch out for the seams, not only to not cause friction but lace and some threads. Hibiclense for affected areas. I use disposable razors for any shaving and change often. I had my favorite shaver but kept getting sores that spread because of using the same one over and over and any nicked.skin. I use Spironolactone which helps from getting in grown hairs. Just a few ideas to ponder.

I stopped using creams and ointments that have a "greasy" consistency because like acne, the consistency adds oil to the sore. I was actually told to use hydrocortisone 1% because it will relieve pain and "dry out" any oily or greasy skin or sores.

I, like you, have had lesions that last for a long time. On here I saw a suggestion of adding a higher dose zinc supplement and washing with Hibiclens. Both have worked wonders for me. I was supposed to have a derooting procedure done on mine, but I canceled the appointment because (knock on wood) my symptoms have cleared up.
