Anyone ever have heat rash?

I have small bumps over both of my arms and I think it is heat rash. Have you ever had it before? How long before it went away? Did you put anything on it? Thanks in advance.

Re: Anyone ever have heat rash?

I used gold bond ointment. It helped with the itching. I don't remember how lng it took to go away. I am not sure if it was a heat rash or an allergic reaction to the sunblock i was wearing. i got it last year all over my checst while on my honeymoon. I guess it was like a week or so before it went away.

I have gotten this on my arms and chest on vacations before. I usually take tylenol, etc. bc it is an anti-inflammatory and put cold compresses on it to relieve the burning. Not sure of any medicines that work...look on webmd.com

A week for this to go away?

They got a little lighter today but still visible and bumpy. They are only from my elbow to hand on the inner part of both of my arms. I have never had this before.

Re: Anyone ever have heat rash?

I get it. I found this online--there are three types. You may want to go to the doctor if it continues--I once had a rash I thought was heat rash, but it was a staph infection of the hair follicles and I needed an antibiotic for it to clear.

The three types:

Miliaria crystallina. The mildest form of heat rash, this affects the sweat ducts in the stratum corneum, the topmost layer of skin. Miliaria crystallina is marked by tiny, clear, superficial blisters and bumps (papules) that break easily but aren't itchy or painful. It usually clears on its own in a few days but can come back if hot, humid weather persists. And though it's most common in newborns, adults can develop it, too, especially if they've recently moved from a temperate climate to the tropics.
Miliaria rubra. Occurring deeper in the outer layer of skin (epidermis), miliaria rubra causes red bumps that are intensely itchy or prickly, giving rise to its common name, prickly heat. There is often little or no sweating in the affected areas (anhidrosis). Adults can develop miliaria rubra shortly after they're exposed to hot weather, but the rash more often appears after several months of exposure. Infants usually develop this type of heat rash between the first and third weeks of life.
Miliaria profunda. A less common form of heat rash, miliaria profunda occurs mainly in adults who have had repeat bouts of miliaria rubra. It affects the dermis, a deeper layer of skin, and appears soon after exercise or any activity that causes sweating. The lesions are firm and flesh-colored, much like goose bumps. Though it's not uncomfortable, miliaria profunda can cause a widespread lack of perspiration, leading to symptoms of heat exhaustion, such as dizziness, nausea and a rapid pulse.

When to seek medical advice
Heat rash usually heals on its own and doesn't require medical care. See your doctor if you or your child has symptoms that last longer than three or four days, the rash seems to be getting worse or there are signs of infection such as:

Increased pain, swelling, redness or warmth around the affected area
Pus draining from the lesions
Swollen lymph nodes in the armpit, neck or groin
A fever or chills

Treatments and drugs
The best treatment for any form of heat rash is to reduce sweating by staying in air-conditioned buildings or, when that's not possible, using fans to circulate the air, wearing lightweight clothing made of fabrics that "breathe" and limiting physical activity. Once skin is cool, heat rash tends to clear quickly.

Mild heat rash doesn't require any other treatment, but more severe forms may need topical therapies to relieve discomfort and prevent complications. Topical treatments may include:

Calamine lotion to soothe itching
Anhydrous lanolin, which may help prevent duct blockage and stop new lesions from forming
Topical steroids in the most serious cases
