Does it hurt when you sit?  It is probably a boil or just a pimple.  Leave it alone.  Boils and get infected if you mess with them.  If it gets really big and full of puss, you may have to go to the doctor and have it lanced.  Doesn't sound like a boil, because they hurt like Hell.

It really sounds like a pimple to me.  If it goes away quickly, or, if you pop it & it looks like a regular pimple - then it's probably just that - a pimple.  Cold sores do not pop.\n\nAs previous posters have said, Cold sores (herpes simplex 1) itch or tingle before they blister.  The blister might ooze a clear liquid, then it will scab over.  Genrally cold sores take 5 days to 2 weeks to heal.  Cold sores do tend to show up in the same place, but as you get older they will pop up in other areas of your lips.  \n\nIf it is a cold sore - don't worry.  Tons of people have them - most of us became infected as kids.  There are great over the counter medicines (abreva) that do a great job of shortening an outbreak.

If it's been that long and it hasn't gone away, it's probably infected.  You should go to the doctor to have them take a look.

Don't worry, sometimes it is very small when you are not aroused. When you get aroused it will grow, and the smaller it is when your not aroused, the more it will grow when your are aroused.

Definitely, get it looked at by a doctor ASAP.  It could be the start of skin cancer which is easily treatable if not left too long.  If left it can spread and be deadly.  Not trying to scare you, but overexposure, particularly burning and lingering coloured spots point to something not right.  Rule it out right away...

two things come to mind the first one is possible but less likely - it could be a tumor that is oozing.  The second is more likely I think you may have some sort of STD but who knows.  Go to your doctor and find out what it is and get it treated and dont have sex with anyone.  Oh i suppose it could just be a zit too depending on how big it is but I doubt it.

It's most likely to be a sebaceous cyst. It's nothing to worry about -- I get them from time to time. I sometimes get them in my earlobe. Squishing them can break them up but makes them last longer. In all but one case they went away by themselves, but sometimes it's months before they're gone.\n\nIt may also be an insect bite or even a very large, nasty pimple.\n\nSebaceous cysts most often arise from swollen hair follicles. Skin trauma can also induce a cyst to form. A sac of cells is created into which a protein called keratin is secreted.\n\nThese cysts are usually found on the face, neck, and trunk. They are usually slow-growing, painless, freely movable lumps beneath the skin. Occasionally, however, a cyst will become inflamed and tender.\n\nSymptoms...\n\n> Usually a nontender, small lump beneath the skin\n> Redness, tenderness, or increased temperature of the skin over the area may occur infection\n> Grayish-white, cheesy, foul-smelling material may drain from the cyst\n\nSigns and tests...\n\nIn most cases, your physician can diagnose a cyst based on its appearance. Occasionally, a biopsy may be needed to rule out other conditions with a similar appearance.\n\nTreatment...\n\nSebaceous cysts are not dangerous and can usually be ignored. At times, they may become inflamed and tender. Others may grow large and interfere with day-to-day life. In these cases, you can have them surgically removed in a physician's office. Alternatively, small inflamed cysts can be treated by injection of steroid medications.

Its normal! It may even turn gray. Just be sure to keep it clean by rinsing your mouth every so often.

It sounds like it may be a planters wart. If so you will have to see a doctor to have it cut out. Good luck.

since it is isolated to the shoulder area, it sounds like its not an infectious disease. it sounds more like an allergy.

No it was not yeast.  It was most likely a pimple and nothing more.  Next time don't pop it though as you don't want to spread the bacteria to some other place.

It could be an ingrown hair!  Sometimes they have a way of just showing up.  Is it sensitive to touch?  Is it red in color and look infected?  Need more info.  Check out ingrown hairs online and see if it matches up with what you are experiencing.

Don't try to self diagnose because it could be a number of things. Go see your regular doctor or dermatologist. Good luck and take care.

It may just be an ingrown hair. You should see if anything will come out of it by lightly queezing it. Don't press too hard and not if it hurts badly. If you get puss that doesn't look like a zit, it may be something worse than an ingrown hair. Wash with peroxide, put neosporin and a band-aid on it then go to a Dr if it doesn't start to heal within a day.

If it is a pus filled pimple like cyst, it could very well be a pilonidal cyst.  It is thought that it is a residual gland of some sort and often at its core is a small curled hair.  It is long lost evolutionarily speaking but, like your appendix, it still hangs around.\n\nYou get it when that small sac become infected.  It will be about twice the size of a pimple on your face and contain a mixture of blood and pus.  If you pop it, you run the risk of a serious infection, so a doctor (a dermatologist, for example) should lance it.  \n\nHowever, if yours does pop or if you squeeze it until it pops, use alcohol to clean the wound.  Getting an infection that close to your spinal column is not a good idea.  \n\nI get them about once every 4 or 5 years.  They hang around for a week or 10 days then disappear.  \n\nBest advice:  don't play with it and go to your doctor.\n\nAdded information then:\n\nGoodness, if this is just a pain with no obvious cyst forming, it may, in fact, not be a pilonidal cyst as the cyst (or abscess, to be exact) is primarily an infection.  These things tend to be very sore and the pain is very sharp with sitting often a problem.  \n\nHowever, with no discharge and no swelling, it may be something else.  \n\nSo, bottom line (so to speak) is I'd see my doctor.
