I would be pleased to answer your question .
From the description of the lesions they seem to be either a acute contact eczema
Avoid scratching as much as possible. It can occur localised as in your case.
Here is what will help:
1. Fluocinolone cream : apply over the affected twice a day for 7 days. The specialist to see will be a dermatologist
and he or she can prescribe these for you. Nothing over the counter will help much, the only product with some benefit is 1% Cortizone cream.
2. Tab Claritin
10 mg twice a day for 5 days
Lastly keep the affected areas as well moisturized as possible with a moisturizer of your choice.
Please feel free to ask if you have any queries.
