Question 1

what could cause a persistent itchy rash in only one armpit that has lasted for at least two months but hasn't spread?

Accepted Answer

ARMPIT RASH: WHY UNDER ONE ARM I DON'T KNOW.
IF ITS UNDER THE ARM THAT DOES ALL THE WORK, LIKE WRITING, LIFTING, EATING, ETC., IT MAY BE A CONTACT DERMATITIS FROM SOAP, DETERGENT, STUFF YOU MAY BE PUTTING ON WITH YOUR DOMINANT HAND.
BE A DETECTIVE AND IF IT DOESNT GET BETTER, SEE DERMATOLOGIST.

Question 2

how does one get rid of an armpit rash?

Accepted Answer

1st things 1st: You need to have a proper evaluation that will first exclude potential precipitators of the rash, such as antiperspirants, and try to find any other etiology of the rash. Thereafter, an appropriate treatment prescribed. Consequently, in order to treat the rash, a physician should evaluate it and give you appropriate treatment.

Question 3

what could causea large red armpit rash under only one arm for over3 wks?

Accepted Answer

Variety of Things: This could be related to clothing you have worn, a hair follicle/ingrown hair, an infection in a sweat gland, a reaction to something that touched that portion of your skin, an infection in your skin, or something else.  It is difficult to tell without more of a story/seeing the rash.

Question 4

my boyfriend has a rash growing underneath his left armpit and is spreading to his right one. there no lumps or anything just kind of red, and he says it burns

Accepted Answer

Hi. : Hi. I cannot diagnose the reason for the rash in your boyfriendâ€™s underarm.  What are possible reasons? Has he started using a new soap or deodorant that he might be reacting to?   Is he wearing clothes that fit tight at the underarm and are causing friction?   If either of these might be the culprit, stop using the new product or try wearing clothes that are looser near the armpit. Wearing clothes that are made of natural fabric like cotton may also be beneficial as it will allow for better ventilation.  Good hygiene is also important. Ensure that the arm is dried off well after washing.
      If his rash does not improve with these suggestions, he could have a fungal infection.  Because the underarm is moist, warm and does not get much air, it is the perfect place for a fungus to grow. He may need to see his doctor to be evaluated.

Question 5

my 3 year old son has a rash in both armpits and behind both knees. they itch. his armpit ones are spreading. what could this be?

Accepted Answer

Sounds like it: could be eczema, a contact rash or a fungal infection. For the first 2, the treatment would be a cortisone cream and for the third an anti-fungal cream. If he is otherwise well, you could try these over-the-counter and if not better, or worsening or appears ill in any way, I would recommend seeing his pediatrician.

Question 6

i have a rash on one armpit, its little red bumps with heads and there is one bump that is very swollen even under the skin. it is painful and itchy?

Accepted Answer

PAINFUL ARMPIT RASH: IF IT HAS BEEN THERE FOR AWHILE SEE YOUR DOCTOR. IT COULD BE SHINGLES.

Question 7

have pain on armpits for 3 days. 4th day, cluster of rash on chest. 7th day, spread to armpit. one doc said shingle.  can it be hiv rash or worse?

Accepted Answer

Nothing Scary: Nope.  Not in any way can this be HIV rash... It is one sided, an expert already told you it is shingles. Take your shingles medicine.

Question 8

i get a bright red, burning rash on my armpit; occasionally it's sore. i've changed deodorant to one w/out phthalates, aluminum, etc; still happens. i use medicated powder to clear it up (something like gold bond medicated powder). what can i do?

Accepted Answer

: Stop all deodorants for a while. Use only powder as deodorant for now. See dermatologist for evaluation and treatment with appropriate topical cream. Eventually you might try an unscented, mild anti perspirant.

Question 9

i have a thick rash only on my left arm pit. what should i do? the rash is not one big rash. it is spred out in 4 different rashes & bright red.

Accepted Answer

Get the diagnosis: There are many types and causes of skin rashes.  Several types of inflammatory conditions of the skin, allergic reactions, and sometimes bacterial, viral or fungal infections can cause rashes on the skin. Insect bites can also be the cause of a rash on the skin.  Have it evaluated by a professional and get the appropriate treatment.

Question 10

left arm keeps breaking out in eraser-sized rashes each one is made up of many small bumps. once i even felt the rash pop up out of nowhere. thoughts?

Accepted Answer

Rash: Rashes are hard to diagnose sometimes when you are looking at them.  Impossible to diagnose without even seeing them.  You need to see your doctor.
