Hi Kevin I feel your situation. I'll inbox you, mate, and we can discuss all your concerns, if you like. I'm no doctor, but I've dealt with moderate acne, and kicked depressions ass to the kerb. I'm willing to help, if you're open to it?
I agree with Exning. Sounds like a cyst. I've had a couple removed myself, lilpurrp. It's nothing to get seriously worried about, they're just clogged pores that have sealed over with skin. Best bet is to see your doctor to see whether it's worth removing. Just don't try to pop it yourself! If it gets infected, they can become very uncomfortable. Hope this helps. Have a great day!
