Pimples, boils, cysts on my armpit and crotch area.

It sounds like you guys have H.S. I can't spell the full out word for it but I had this issue FOREVER started right about 12-14 years old and it took years or researching and I fidnally learned about HS and when you google it it's pretty gross and shows the worse cases but I went to a dermatologists and she confirmed that's what it was. I was put on medication to help and it went away 100% but then bc I'm allergic to a lot of medication I had to stop using it :( but I got a topical gel to use twice daily in top of antibacterial body soap and it says helped sooo much! Along with controlling stress, regularly exercising and eating super clean :) There are lots of ways a dermatologist can help and lots of remedies online if medication isn't for you

i have some pumps under my armpit im 11 and everyonce in a while they go away and come back i dont know if this is because of puberty or what

Try Peragel 10, it doesn’t irritate and calms the skin down almost immediately

I also suffer from HS. I am a female 47 years old, these cysts started when i was about 13. After MANY years of suffering physically and emotionally (and luckily fewer outbreaks) I can tell when a new cyst will be coming up. There are many good advisors from what I've read - my only additional input is for sufferers to try not only keeping your skin clean and dry but to apply a compress of natural raw honey (under a larger band-aid ) for several days on the cyst. Honey is natural antibacterial and it will heal and soothe the inflammation. I have had quarter size cysts shrink down in a few days. It also prevents scaring from being horrible (A huge plus
