Welcome to justanswer.
Your symptoms are simulating fungal infection these are quiet characterized by itching and dandruff. Antifungal shampoo like nizoral (ketoconazole) can be extremely helpful in your case. I think this treatment should provide significant relief in your case. For time being you may consider use of antihistaminics.
Please ask if i have left any of your query unanswered or if there are any doubts.
Routinely no tests are needed or asked in case of dandruff (fungal infections), its a clinical diagnosis. And it is the foremost and commonest cause of scalp itching, dryness, and scaling. I think this cause should be ruled out before considering any other cause.
I would suggest you to use nizoral shampoo which should be helpful and that will confirm the cause.Its pretty common to have such infections and respond well to treatment.
I hope that answers your question.
Yes itchy skin behind ears and on neck can be due to same reasons. Some patients may even have itchy eyebrows.
No surely they are not due to same reason.
Please describe these symptoms and associated complains in detail so that i can help you?
Is rash associated with it?
Any history of allergy?
Thanks for inputs.
From symptoms i think its type of dermatitis. Local corticosteroid creams should provide relief in that case. I think you should give try to this cream and if symptoms persist i would suggest you to see a dermatologist.
You can take following precautions
Take brief, lukewarm baths. Apply lubricant immediately following the bath. Keep your fingernails filed short. Select soft cotton fabrics when choosing clothing. Consider using antihistamines to reduce scratching . Keep yourself cool; avoid situations where overheating occurs.
