I have over 12 small round (not perfectly circular) lumps, different sizes, on both arms, neck, & couple on legs. Are not pimples. Dr. Dismisses.?

Ask family members: In the absence of associated pain, rapid growth or any discharge from these lumps there is no urgency to have them removed. Possibilities include include cysts or lipomas(benign fatty tumors) but a biopsy would give more information. These types of lesions can be associated with inherited conditions so it's useful to ask family members if they have similar lesions, then follow up with your doctor. ...Read more

Chickenpox? Staph?: Chickenpox usually involves face and trunk as well as arms or legs. But the rash appears in crops and "red, pus filled pimples" is typical. If he has been properly vaccinated, including chickenpox, it's something else. A staph or strep infection is possible. Whatever the cause, it needs medical attention right away. Call his pediatriican's office today; even over the weekend, someone is on call. ...Read more

Keratosis pilaris?: Sounds more like keratosis pilaris, small hard plugs at the opening of every follicle. Commonly seen on backs of upper arms, sometimes cheeks, sometimes front of thighs. I usually recommend my patients try gentle cleanser such as dove or cetaphil, and apply eucerin plus lotion or amlactin at least twice daily. It takes a few months to clear. If that doesn't work, I use a prescription med. ...Read more

Pinky Tiny Pimples-like Rashes on the back of both hands & starts to feel itchy after few hours...spreading to arm slowly...can I take Cetirizine?

Pinky Tiny Pimples-like Rashes on the back of both hands & starts to feel itchy after few hours...spreading to arm slowly...can I take Cetirizine?

You could but..: a better choice might be diphenhydramine (Benadryl) but the cetirizine is less likely to make you drowsy so you can start with that and if it doesn't work try the diphenhydramine. You can also try 1% hydrocortisone cream that you can get at the store on the rash to see if that alleviates the itching and the spread of the rash. ...Read more

I have a pimple like rash only on the outter part of my arms it not itchy but it is really bothersome. What is it? I have had it for about a month now

Rash: It's very difficult to diagnose skin rashes without a picture, but it could be patches of eczema (which don't always have to itch). If it's symmetric on the upper arms, we think of things like keratosis pilaris, which doesn't itch, but can be cosmetically bothersome. It doesn't sound like an urgent concern, and getting it checked in the next 1-2 weeks should be fine. ...Read more

I have a rash that start off as a small pimple and evolves to look like a burn mark. It's on my  legs, waist, arms(severe) and neck. What can this be?

Exanthems (= rashes): such as yours are often impossible to diagnose with out the MD having the advantage of " laying eyes on it." Photos of good resolution can help but won't supplant good clinical evaluation. There are so many possibilities it wouldn't help anything to try to narrow down with such little information. On the other hand, a good dermatologist usually can nail it in a few minutes in person. ...Read more
