I get them in my arm pits. They come for a few days and hurt so bad i can barely move my arms and then they go away or at least the pain does for a few day, but then the roller coaster starts all over again. I wonder why we get them?

No I haven't, but I will now. Thank you :)

Have either of you ever looked up Hiddradentitis Suppurativa? It is thought that it is also auto-immune and can seem like cysts in arm pits, groin, anywhere really. Might be worth looking at if you get them frequently in those areas
