Hello
Thank you for the pictures.
From the review it seems you are having urticaria which is an allergic skin rash.
Before I could conclude my diagnosis, I would like to ask few questions:
1. Does the lesions itch and are they painful?
2. Do the lesions disappear after few hours? Are they ever persistent for more than 24 hours?
3. Is there any history of swelling around eyes/lips?
4. Any particular activity after which such rash usually appear? ( Food, Medications, exercise, temperature, etc )
Hope you will revert soon with the details asked for.
Thanks

Brief Answer:
Oral antihistaminics for long duration

Detailed Answer:
The history suggests that you are having chronic urticaria.
Its an allergic manifestation of skin, where an allergen leads to release of certain substances from your blood, leading to itchy skin rash and swelling over soft tissues.
Its proper management requires thorough history, clinical and laboratory work-up.You may have to go for specific tests like patch test, food prick test, IgE antibody levels etc.
As for treatment part, best would be the avoidance of allergen as far as possible. Try to eliminate possible triggering foods from diet.
I would also advise you various anti-histaminics (Desloratidine, Levocetrzine etc) for long duration( atleast 3 months) with or without oral corticosteroids.
Apply soothing calamine lotion over rash thrice a day.
For non- responding cases there are many other drugs like dapsone, cyclosporine, montelukast, omalizumab etc which can be used in certain selected cases.

Thank you
