Question 1

itchy rashes under armpit, what are possible causes and otc treatments? i shower daily, don't shave.

Accepted Answer

Dermatitis vs fungal: An 'itchy' rash in the axilla (arm pit) may be a 'contact dermatitis' or a yeast/fungal infection. An otc treatment for dermatitis is Cortaid (hydrocortisone 1%) and the treatment for fungal infection is otc 'anti-fungal' e.g. Lotrimin (clotrimazole). Dermatitis may be caused by exposure to chemicals/fragrances in deodorant/anti-perspirants so a hypo-allergenic subsitute may be needed.
Get seen if no better.

Question 2

why histamine surge cause heart pain in swimming? i get armpit rashes if exercising 1min. i get moderate pain in heart in 45min so have to stop.

Not from histamine: Despite your age, you need to get  your cardiac status evaluated before you exert heavily again. This may be a warning sign of something serious and potentially life-threatening.

Allergic reaction: Personal care items like deodorants or body creams can some times cause allergic reactions with blistering.  If it is only on one side and painful consider a viral infection.

Hidradenitis: This is probably hidradenitis suppurativa . Your dermatologist can help you.

Question 7

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.

: quite often this could be a contact allergic or irritant dermatitis. Suggest that you d/c your current deodorant for a while to see if it improves on its own. If not, see dermatologist for eval and poss tx

Question 9

my son has a rash on both his thighs that at first we thought was caused by his nappy but its now spread to his armpits . its not responding to tropical creams ( clotrimazole) and its been almost two weeks now . help?

Accepted Answer

Likely requires exam: Rashes are often only properly labeled &amp; treated after a review of the history and a direct exam. Sometimes a doc could provide guidance with review of good photos. This site does not support such submissions but you may have a doc in your region that does telemedicine.

Question 10

what would cause a red rash behind both armpits? i just had an iud (paraguard) inserted on the 11th.  could that cause this painful rash?

Accepted Answer

Local Irritation?: If it is symmetrical on both sides, think about local irritation from clothing or a bra.  Have you used a new soap or perfume or other skin product with dye in it? Do you take any other medicines? I would not be suspicious of the IUD causing this kind of discrete rash.
