Brief Answer: Id eruption, Treat underlying cause Detailed Answer: Hello and welcome to healthcaremagic. I am Dr. Kakkar. I have gone through your query. After going through your query and having a look at the pictures, I could make out that you have Infected Eczematous dermatitis (IED)of the hand, Hives and Atheletes foot(I could nt find the photograph of atheletes foot). Your treatment history includes: oral antibiotics, prednisolone, antihistamines. I would keep a possibility of "IED with Athelete's foot with Id eruption with ??Hives" as the reason for generalized rash. Urticaria or hives can occur due to various causes like(to name a few): --Infections(bacterial , viral, fungal) --Drugs(Pain killers/ antibiotics etc) --Certain foods and food additives/preservatives --Physical Urticaria: Cold temperature, Heat, Pressure(Prolonged Standing, Sitting), Dermaographism etc. --Cholinergic Urticaria: in response to strong emotions, exercise, spicy food etc --Autoimmune disorders like SLE, RA etc. --A few cases have no underlying cause and are known as idiopathic urticaria. I would advice you to get few basic lab tests like Hemogram, stool for ova/cyst, Urine routine, Chest X-Ray. An oral antihistamine like Fexofenadine (Allegra 180 mg tab) OR Loratadine (Alaspan 10mg tablet) once or twice daily for a week would be suitable. They are non-sedating and wont affect your alertness level. If I was your treating doctor I would have also given you a shot of injectable antihistamines like Avil(pheniramine) and Injectable effcorlin(hydrocortisone) for rapid relief. A topical soothing lotion like calamine would help you symptomatically. Another possibility that I would like to keep is a "Generalized Id Eruption" which is a sort of hypersensitivity reaction to an infectious focus(bacterial, fungal etc) in the body, manifesting in the form of generalized rash. Apart from managing hives/Id Eruptions, you need to take specific treatment for Athelete's foot and Infected Eczematous dermatitis of the hand because Infection(bacterial, fungal etc) are an important cause of both urticaria as well as Id eruption. Just managing urticaria or Id eruption, symptomatically with prednisolone and not addressing the real underlying cause(Infections) would provide only temporary relief. If I was the treating doctor I would have started you on oral+topical antifungals for Athelete's foot along with oral antibiotics and topical combination cream/ointment of steroid + antibiotic (clobetasol+fucidic acid) for application over the eczematous dermatitis present on the hand. A short course of prednisolone for a week or so, is warranted in your case to overcome the generalized Id eruption rash/ Hives. Since Id eruption can have a few relapses usually till the infection is well controlled with antifungals+antibacterials, therefore my explanation for recurrent rashes is Id eruption rather than Hives in your case.
