Welcome to Healthcaremagic forum,
To give you the right picture of the problem ,I would like to know the exact location of these itchy lesions .
Is the groins involved here ,or is it just the dorsal aspect of the thighs involved .
If the groins are involved then must be a fungal infection
,and you would require a antifungal tablet or a lotion to get it cured.
If only thighs are involved then could be dry skin
or even scabies
For dry skin you should try lot of moisturizers .
For scabies you have to try permithrine lotion all over the body.
To begin with you can take oral anti histaminic tablet like cetrizine
and see the response .
A detail history and a picture of the lesions would help me further to guide you better.
hope this advise helps you .
wish you good health .
