Well i attended a doctor, and as i had thought i have what he called sebaceous cysts on my penis(or sebaceous glands) now there was one very large and inflated one that i got an antibiotic for and am now off. it did shrink the size but not completely, and it seems the edges of it didnt shrink as much as the center so now it looks like i have a crater(sp?) in it.... what im askin is should i get surgery for this because mayb the wall it's built will not go away? or is there other antibiotics that may help(lost what that antibiotic was called)
Sebaceous cysts aren't the same as normal sebaceous glands, which everyone has over most of the skin, and which, though usually buried in the skin, are often visible as tiny bumps in the thinner skin of the genitalia. Sebaceous glands secrete sebum, a white gunk that's a natural skin moisturiser.
If the opening of a sebaceous gland gets blocked, usually the gland dies and you get a whitehead, but sometimes the gland keeps producing sebum and swells bigger and bigger. That's a sebaceous cyst. It appears like a large, deep pimple. Usually if you let them alone the gland does eventually die and shrink, over a period of some weeks.
If you were prescribed an antibiotic for a sebaceous cyst, it must have become infected. An infected sebaceous gland is a zit; an infected sebaceous cyst would be a super-zit. Scarring would be a possibility. Antibiotics wouldn't help reduce scarring. Time will make it better. Cosmetic surgery might be possible, but I'd see what it looks like after three months first - it may be much improved and not worth fiddling with. There's always a risk that surgery to reduce scars will make them worse.
