Hello Welcome! I would be pleased to answer your question . From the description of the lesions they seem to be either a eczema or irritant contact dermatitis. The Allergy can be due to external or internal allergic agent. Here is what will help: 1. Clobetasol propionate cream + Mupirocin cream: Mix and apply over the affected area on the right shoulder twice a day for 5days then switch to Fluticasone propionate cream once at night for 2-4 weeks. In the groin/upper inner thigh use Fluticasone in place of Clobetasol from the beginning. 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. Syrup Claritin twice a day for 5 days to get relief in itching. 3. Sarna sensitive lotion can be used 2-3 times a day to give further relief from itching. This can be continued even when the above creams have been stopped. 4. Avoid scratching the affected areas as much as possible. This is most important. Whenever it is not bearable soak a towel in ice cold water and keep it on the affected areas or apply the Sarna sensitive lotion. Lastly keep the affected areas as well moisturized as possible with a moisturizer of your choice. NOTE: 1% Cortizone cream, Claritin and Sarna lotion can be bought without a prescription. Please feel free to ask if you have any queries.
