4 months ago my 12 yr old grandson developed red bumps on

Customer Question

4 months ago my 12 yr old grandson developed red bumps on his back. It spread to his stomach, the bumps grew to more of a rash type appearance. It has now spread to his butt, down his thighs, with a few starting below the knee. When he sweats the itch is unbearable. Seems to start with small skin eruptions. Do not believe it is an allergic reaction. Any thoughts?
JA: How long have you been dealing with this? Does anything in particular seem to make the bumps better or worse?
Customer: Starts as bumps, turns into large flaky patches. Sweating makes it itch.
JA: Anything else in your medical history you think the doctor should know?
Customer: Healthy, active 12. Yr old boy.

This is Dr. David

this sounds like it could be from eczema or from a viral infection

can you upload a clear jpg photo of his rash so I can better help you?

Customer: replied 5 months ago.
Current pics taken last night.
Expert:  Dr. David replied 5 months ago.

does he have a fever?

has he had chicken pox before?

he can get blood test to check for chicken pox infection.

he should see a doctor and get blood test to check for elevated WBC count and infection.

he may need hydrocortisone cream to help decrease itchiness.

milk baths or calamine lotion could help.

Customer: replied 5 months ago.
Took him to a walk in clinic. They have no idea what it is, did a scraping, not fungal. Prescribed steroids.
Customer: replied 5 months ago.
No fever, yes had chicken pox. We can relieve the itch, but it containers to spread.
Customer: replied 5 months ago.
Continues to spread.
Expert:  Dr. David replied 5 months ago.

most skin rashes are caused by viral infections

and many causes of rashes are not found.

rash can often be a cutaneous manifestation of internal inflammation.

just a viral infection internally can cause a skin rash.

most rashes over time go away on their own.

that is good you have the itch under control

that is good he has no fever.

is he able to sleep through the night?

steroids should always be taken with food in the stomach.

Customer: replied 5 months ago.
He sleeps fine, eats fine, feels good. Until the itch kicks up.
Expert:  Dr. David replied 5 months ago.

that is good he has no fever.

some viral infections may not cause fever.

it may take 1-2 weeks to go away

Customer: replied 5 months ago.
He has had it for 4 months now as it continues to spread. You do not think it is an allergic reaction?
Expert:  Dr. David replied 5 months ago.

4 months is a long time

yes, he should see an allergy doctor and get skin allergy testing.

and see if anti-histamines like benadryl, allegra, claritin can help his symptoms.

Customer: replied 5 months ago.
Unclear now if he needs to see a dermatologist or allergy specialist? Searching the web, pictures of Pityriasis Rosea, seem to be similar.
Expert:  Dr. David replied 5 months ago.

I think he should see an allergy specialist

take him to a dermatologist. I think that will prove to be less fruitful.
