Those are most likely boils and they are caused by the staph bacteria.  Use a warm compress on them several times a day to get them to open up.  If they don't open on their own or you get them often you may need to see the doc to get them taken care of and to get antibiotics for them.  They have nothing to do with cancer and some people are  more prone to boils than others.

it could be a cyst, it's sort of like a huge zit. may have been caused by an infected hair. cyst usually form on butts behind ears or armpits. It will hurt pretty bad until it shrinks or pops- if yours has a head- it may be ready to drain. put hot compresses on it and after about 15 minutes it should drain.

that could be what's referred to as "milk bumps" or it could be a form of acne...either way I doubt it is serious...I always say if you are concerned be sure to mention it to your doctor the next time you are in.  I doubt it's anything for cause of alarm though...if it is milk bumps to my knowledge there's nothing that can be done for it...it's just a type of skin alot of women have especially if you happen to be fair haired...if it's acne normally the dr will send you to a dermatologist and he can prescribe something for it.  It might also be a form of ingrown hair.

Oh GOD, don't cut them off! They're likely something called "Pearly Penile Papules," which are not harmful and are not contagious. It is unknown why some men have them, but a great deal of the population does. You're all right.\n\nUnless they are pimple-like and pus-filled, then you need to see a doctor. If they are painful, see a doctor. PPPs should not burst or be filled with pus.

there could be some infection there. Just put a clean dry dressing on every day. do not use neopsorin on it. This just keeps the area wet. Give it a couple more days. What you could do is take a pen and mark the area of redness on your arm and if the redness goes out of this area you know it is getting bigger and should probably get on an antibiotic. Sometimes the trauma to the area can cause it to be red. This is not always a sign of infection. If you start to notice a large amount of puss like drainage and redness, then get to a dr.

Sounds like PK. Very common.\nThe K stands for keratosis, I forget what the P stands for.\nYou get red dots or bumps on your arms sort of like pimples but they aren't.\nGet some Aquaphor cream in a tube at the drugstore. It works like a charm if you put some on the spots every day.\nIt costs about $5.\nNOthing else works for this, I know, I have it.

are you sure a sweat gland is swollen or is it a lymph node?.....best to be checked out...but not by a dermatologist....she should see her pediatrician first....but if she uses sick deodorant that could be the culprit....roll on is better....doesn't clog poors as bad.....good luck.....

a boil is a painful, circumscribed pus-filled inflammation of the skin and subcutaneous tissue usually caused by a local staphylococcal infection, while a pimple is just a small inflamation of the skin caused by a bit of bacteria trapped undernearth the skin

You should see a physician for an accurate diagnosis. Going to Yahoo answers with a hard to understand question is not the best option.\n\nThe two problems could be unrelated.\n\nThe lump could be anything ranging from a pustule, abcess, enlarged lympnode to some sort of mass. A doctor would need to examine.  The itching could be irritation from clothing and sweat, a fungal disease, STD, parasites or any number of things.  \n\nOne visit to the doc will provide you with answers and treatment.

Boils are bumps in the skin which are often filled with pus.  Boils are formed under the skin when the hair follicles are infected by the staphylococcus aureus (staph) bacteria . More info on boils and home remedies for boils available at http://ailments.in/boil.html

Sounds like cysts.  They are like enormous pimples that are very painful.  Use a warm, damp compress on them 2-4 times per day to ease the pain and inflamation, and see a doctor as soon as you can.  Best to you.

Etiology\n\nThe perianal skin tends to itch. Pruritus ani has many causes: (1) dermatologic disorders (eg, psoriasis, atopic dermatitis); (2) allergic reactions (eg, contact dermatitis caused by local anesthetics, such as "-caine" preparations, various ointments, or aromatic and other chemicals used in soap) and eczema after ingestion of certain foods (especially spices, citrus fruits, vitamin C tablets, coffee, beer, and cola), although it is doubtful that true allergy is a causative agent; (3) superficial infections with fungi (eg, dermatophytosis, candidiasis) and bacteria (secondary infection caused by scratching); (4) parasites (pinworms and, less commonly, scabies or pediculosis); (5) oral antibiotics (especially tetracyclines); (6) disease processes, such as systemic diseases (eg, diabetes mellitus, liver disease), proctologic disorders (eg, skin tags, cryptitis, draining fistulas), and tumors (eg, Bowen's disease, extramammary Paget's disease); (7) hygiene, either poor with residual irritating feces or overmeticulous with excessive use of soap and rubbing; (8) warmth and hyperhidrosis caused by tight body stockings, jockey shorts, warm bed clothing, obesity, or climate; and (9) psychogenic response. Hemorrhoids usually do not cause pruritus ani.

If you're worried, obey your instincts and see a doctor.  \nIt could take longer than 3 weeks for a percussive bump to heal under the skin.

exfoliate your arms on a regular basis you might be getting ingrown hairs. It could also be a reaction to wheat products of milk. My daughter gets bumps on her arms when she drinks a lot of milk or has a lot of dairy products. you can put mederma (I think that is how you spell it) on the bumps after they are healed to reduce the scarring.
