Detailed Answer:
Hello Dear Madam

Welcome to HCM!
I am Dr V XXXXXXX Sr Dermatologist.

I have gone through the description and it will be my best effort to solve the problem.

Here under I am listing few measures that you can take while I get your responses to my questions related to the rash:

1 In such a situation, one should avoid synthetic garments, deodorants, perfumes, harsh soaps, or anything that might aggravate the symptoms.

2 Please enlist the medicines that have been taken apart from the ones that were taken to deal with the current problem

3 Tab ZYRTEC 10mg 1 tab Once Daily at bedtime for 7 days , an antiallergic might be taken for control of symptoms.

The following information will help in better understanding of the problem from long term perspective:

---Has such a problem occurred for the first time
---Did it follow some activity or any food or any change in your routine
---Since you've already mentioned its severe so how long does it last?
---How frequent it is and what time of day/night does it become more intense
---Any other family member having similar complaints
---Response to medicines taken so far

I am expecting your reply and will revert to you on priority.
Best wishes.
