Detailed Answer:
Hello and welcome to healthcaremagic.
I am D. Kakkar. I am a
dermatologist and I would like to help you regarding your query.
Hives(Urticaria). They are pale or red raised patches that may itch and are evanescent i.e the rash appears suddenly and may involve the whole body and then usually resolves within a few hours.
Urticaria OR hives can occur due to various causes like(to name a few):
-Infections(bacterial , viral, fungal)
-Drugs (painkillers, 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 Xray.
An oral antihistamine like
Fexofenadine OR
Loratadine once or twice daily for a week would be suitable. They are non-sedating and wont affect your alertness level.
A topical soothing lotion like
calamine would help you symptomatically.
take care
