Question: I have developed an allergy (of unknown cause) that results in severe itching (almost pricking) sensations all over the body. Its more severe on the scalp, eyes, nose, ears, hands and legs. It is also accompanied by a dry cough (I had a bout of throat infection a month back).

Many thanks for the quick response. Please see my replies:
1) I would like to know whether itch is associated with any lesions on body?
>> No. However, strangely, my father who was visiting my place, developed the same allergy at the same time as me. He has severe rashes and lesions and is seeing a dermatologist (he is back in his home town now). It started off the same way as me (severe itching, and unable to sleep at night due to the same). For me it has stopped at that, for him however it has resulted in rashes.

2) Also kindly tell me if there is associated scaling on scalp or red colored irchy lesions on corresponding sites.?
>> No

3) history of recurrent cold or cough?
>> Yes. The throat infection and severe cough that I had about a month back did not resolve completely. I still have dry cough, and occasional throat pain.

If possible and lesions are present kindly send pic of the lesions so that I can help you to my best.

4) duration of itch ?
>> 2 weeks now. First treatment was for 5 days, upon whose completion, I developed the symptoms again after 2 days of stoppage. I get quite a bit of relief with the medicine, but not completely.

Thanks again.

I have been having (and advised to have) Allegra M for another 10 days at bedtime. Can I keep that as-is, and add the Fexofenadine in addition?
Thanks, again.

Thanks, so I will basically continue with Allegra M for 10 days.
