Try to keep area clean, but do not rub ot it shreds the skin. Wear loose clothing and use cool compresses to keep skin clean. Friction is your enemy.
I use Vaseline to keep skin from rubbing if I can't get to doctor or run out of my meds.

Sweating will make your skin tacky and tear. Stay cool during a flare up. Stay hydrated.
Do not shave the area, if possible use Lazer hair removal so stubble doesn't rub a lesion on corresponding area.

Stress is a trigger. I have had HH since I was 35. I'm now 60. First couple years was hard figuring out what it was and what I could do. I found a great dermatologist in Omaha that had treated many with HH. She is a God send.

Don't let your lesions get infected. Take it easy until they heal.
I hope you have a speedy recovery
