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

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.

Does Oral Herpes blisters show up in the armpits?

Does Oral Herpes blisters show up in the armpits?

It's possible: HSV can occur anywhere on the skin and in the oral cavity. While it's possible for HSV to cause a blister in the armpit (axilla) it is less common. Tissue from scrapings of the lesion can be tested for HSV by immunofluorescense staining or PCR DNA testing.

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.

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.

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.

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 an infection expert or dermatologist. Good luck!

Rash: Above armpit with pain makes one think of shingles. But I can't be sure without an examination. Since there is a treatment to shorten the course of this disease you need to get in right away to be evaluated. Best wishes.

Does shingles always have a rash? I have a nerve-like pain just below my armpit but no rash or blisters. The pain has been longer than 1 week too.

Zoster sine herpete: And that young lady is how we docs say "shingles without a rash." Yes, it DOES exist. And many people are grateful for it since the alternative is have the shingles with all the cosmetic issues. When absolutely necessary we can do spinal taps to identify particles of the virus who are causing the pain and burning symptoms but without a lot of exertion.

Rash: Difficult to say without seeing them but the fact they are so itchy makes me think of hives or bites. Send a picture if you can. Keep them clean and use an antihistamine. All the best.

See your doctor ASAP: It is difficult to tell without looking at your rash and examine your armpits. You may need surgical drainage if you have boils or abscess, and antibiotic if you have cellulitis. Please go to see your doctor or urgent care ASAP for definitive diagnosis and specific treatment.
