See Your Doctor: Your 11 yr. old daughter has blisters in her armpit. Blistering rashes have numerous causes. Having them confined to her armpit is an unusual location and could be caused by local exposure to an irritant, infections, or even poison ivy through touching the area. Because rashes are difficult to diagnose without visual inspection, your daughter should see her doctor for correct diagnosis. ...Read more

What treatment to eliminate the bacteria under the armpit?

No way: You can not eliminate bacteria on the skin. A very high concentration or the presence of certain more pathogenic bacteria can be problematic. In those cases we use anti-bacterial agents such as antibiotics (topically and/or orally) to treat them. Additionally, the use of other topical anti-microbial agents can be helpful to limit the offending bacteria. ...Read more

For about 11 years I have gotten painful blister like bumps on my inner thighs and armpits. Multiple drs don't know what the cause is. Any ideas?

See your doctor: Painful blisters needs to be seen by your doctor to document location, size, and type of bumps/blisters. If needed, they can do a scrape biopsy to find out what it is. By itself, it's hard to determine, and you may be referred to a dermatologist who can pinpoint it right away and take care it. It's impossible to determine without seeing it in person, by your doctor first. ...Read more

Itchy rashes under armpit, what are possible causes and OTC treatments? I shower daily, don't shave.

Itchy rashes under armpit, what are possible causes and OTC treatments? I shower daily, don't shave.

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. ...Read more

I get frequent blisters in my armpits and sometimes in my groin area. I usually just apply antiseptics, and they drain all by themselves after a while, but then they recur. What could be the cause of it?

I get frequent blisters in my armpits and sometimes in my groin area. I usually just apply antiseptics, and they drain all by themselves after a while, but then they recur. What could be the cause of it?

Infection?: "Blister" normally means superficial, filled with clear fluid. I can't explain something like that. Maybe allergy? But if these are deeper bumps that drain pus, sometimes with blood, then you may be having recurrent staph or strep infections. Or maybe a chronic problem called hidradenitis suppurativa. See a doctor, preferably a dermatologist or infectious diseases specialist. Good luck! ...Read more

I have a small little blister looking thing inside of my armpit, but it doesn't hurt what could it be?

Need to be seen: Not enough detail here for correct identification. If it sticks out like a finger, it is an acrochordon (benign skin tag). If it is a lump deep in the skin it is an epidermal syst or tricholemmal cyst. If you shave there it may contain an in-growing hair. Sometimes they have an opening through which you can squeeze out sebum which looks like cream cheeze with a sour odor. ...Read more
