Thanks for writing to us.
Red itchy rashes with a burning sensation and hives spread all over your body as seen in the photograph are most likely an allergic skin reaction.
Such a wide spread reaction needs an immediate attention of the dermatologist as it often causes plenty of fluid loss from the body leading to dehydration.
You have already been given systemic steroids and anti allergics and these have not helped much. This means you are still getting exposed to the allergen.
Stay away from your pet cat as long as possible.
You can help the improvement by
* Avoid scrubbing your skin.
* Use as little soap as possible. Use gentle cleansers instead.
* Avoid applying cosmetic lotions or ointments directly on the rash.
* Use warm (not hot) water for cleaning. XXXXXXX dry, don't rub.
* Eliminate any newly added cosmetics or lotions.
* Leave the affected area exposed to the air as much as possible.
* Try calamine medicated lotion.
* Hydrocortisone cream like Caldecort(1%) is available without a prescription and may soothe many rashes.
The rashes usually take 5-7 days to disappear. Other possible causes that need to be excluded are-
1. Erythema multiforme.
2. Dermatitis- due to skin infection, allergy,etc.
3. Dry skin- Xerosis.
I would suggest to go for a second opinion from a dermatologist as early as possible.
I hope my answer and recommendations are adequate and helpful. Waiting for your further follow up queries if any.
Regards.
