A dermatologist gives five possible causes of itchy red bumps all over your body…

Dr. Janet Prystowsky, board certified dermatologist in New York, NY, with 30+ years’ experience, describes five possible causes, in no particular order.

She explains, “Hives are an outbreak of pale, red, itchy bumps caused by an allergic reaction.

“Contact dermatitis, like the rash you get from poison ivy, occurs when you touch something that you are allergic to as well.”

It may prove to be challenging to figure out just what it is you’re allergic to, if this is the cause of your symptoms.

Dr. Prystowsky continues, “Erythema multiforme is an immune reaction to an infection, drug, or hormones.

“A form of cutaneous T cell lymphoma can cause red, itchy bumps. Widespread red itchy bumps would rarely signify cancer.  However, in the case of cutaneous T cell lymphoma, this does represent cancer.”

Finally, bug bites can cause this symptom, but more likely than not, you’ll know if you’ve been bitten by bugs, such as during sitting outside in the evening, you have to keep swatting away mosquitos and feel them “biting” you.

Most Common Causes

“Most common causes of red bumps are allergy reactions to medications, plants or insects,” says Dr. Prystowsky.

In combination with her focus on early skin cancer detection and removal, Dr. Prystowsky provides a wide range of revitalizing and rejuvenating treatments.
