What Causes Recurrent Itchy Rash On Body?
Question: I have been having a reappearing rash for about two months now. It appears to be tiny red bumps in no kind of pattern and doesn't seep. It first appeared in the crease on the knee in a 1 inch long thin type shape and then disappeared on its own about two weeks later. Now it has appeared again on the underside of my upper arm. I haven't changed soaps of any kind, diet, or been in contact with poison ivy, sumac, or oak or have any allergies . Any thoughts on what it could be
Brief Answer:
Eczema
Detailed Answer:
Hello,
Welcome to healthcare magic.
I have gone through your history and seen your clinical photograph.
I understand that you are having a recurring itchy rash on your body.
I would like to consider the possibility of an eczema.
Eczema, as such is a broad term, could be due to intrinsic or extrinsic factors.
You have mentioned very clearly that you have had no contact with the common allergens.
So, a possibility of an intrinsic eczema like adult onset atopic dermatitis could be a possibility.
Have you had any nasal allergies( allergic rhinitis/polyps) or wheezing either currently or in your childhood?
Have you had a generally dry skin from your childhood days or in the recent past?
Have you had any thyroid problems?
Atopic dermatitis is more commonly seen in individuals with above issues. It generally presents in the creases in adults.
You could apply a mild steroid like hydrocortisone cream twice a day for 10- 14 days on the rash.
Use a moisturizer containing colloidal oatmeal liberally twice a day. Apply it within 3 minutes after bath to trap in the moisture.
Bathe using lukewarm water.
Use a soap free cleanser like Cetaphil cleanser instead of soap and use minimal cleanser.
Hope this helps you.
If you have any other queries, I would be glad to assist.
Take care.
Regards,
Dr. Johny Chacko
