I have the same thing it's really red and itchy so much when I touch it its really sore I have been using sudocrem but doesn't seem to be working
what about on shoulder near neck
It's a pilonidal sinus. There probably is a little hole back there, but you could never find it yourself.
Everytime it gets itchy and red, it's infected with bacteria. So use neosporin.
It will continue to come back every once in a while, but it'll help if you keep it clean, and use that anti bacterial stuff doctors use once a week. A simple surgery will send it away forever.
If you go to a doctor, mention the possibility of one of these, most doctors only check this area for a split second and overlook the problem.
There should be a spot in your buttcrack that ALWAYS hurts if you touch it, you may not feel a lump, but you'll feel the pain. That is the sinus. I'll bet you get little cysts under the skin on your neck too, right?
Celestone cream will stop the symptoms works well, I don’t know which country you’re in but here you need a prescription.
Oh, forgot to mention I've been testing and there is no chance it's an STD (herpes, etc.) so if we could please avoid any of those types of comments. Thank you for you help.
