Question: Dermatology......raised wheals on scalp that itch like crazy; with scratching, can scab over and are slow to heal. Now same problem emerging downward on neck behind and under the ear. Thought it was psoriasis at first.
Treatment shampoos seemed to ease the condition, but it never went away totally. Now with the spread to the neck area of a larger raised spot, the itching is becoming more problematic - also, this is visible and embarrassing as I am a receptionist/nurse in a VA clinic. We have 2 Maltese/poodle dogs with no skin problems to my knowledge. What could it be? What to do?

No diabetes; no hair dye; no oral meds. Observe healthy diet and exercise moderately. The scalp problems have been occurring over quite a long period of time.
The scalp lesions form as round raised itchy spots surrounded by pinpoint red spots, not connected to the main one. Unable to download pictures, but illustrations are similar. The affected neck area is a new happening. What medical treatments are suggested? Will a heat lamp help?

Brief Answer:
Seems to be dermatitis, heat lamp won't help

Detailed Answer:
After going through your history it seems to be dermatitis.
If I was your treating doctor I would recommend you to use a ketoconazole shampoo twice weekly and apply lotion containing combination of steroid and antifungal like beclomethasone and clotrimazole lotion on the affected areas of the scalp and neck twice daily.
For itching you can take antihistaminic like tablet Cetrizine 10 mg twice daily.
I don't think heat lamp will help.

My son had a small red itchy bump at the edge of his bottom a few days ago. We thought it was a bug bite. He scratched it and it got bigger and scabbed over. Now it is itching more, has a red area around it, and he has a few more similar bumps near it (also itchy). No other bumps on his body. Any ideas?

My 4 year old son was stung on the top of his ear this afternoon. That area has turned purple. Is this normal? Or a sign that he might be allergic? I don't know if I should take him to the doctor or just ice it. What do you recommend?

Thanks in advance!

Dear Doctor,
Early morning I sneeze continuously almost 1-2 minutes.after that I feel very uncomfort and my nostrils gets blocked.
Only after 2-3 hours I could be able to have the normal position. What is all about this and what should I do to get rid off from it.
