I am a 40y/o woman. Pretty healthy all these years. No preexisting conditions. I live in Florida. A month ago I started to suffer everyday of this weird "rash" and bumps that last for 1 hour or so and then disappear slowly first the itchiness- rash and then the bumps in 3-4 hours, faster the rash and itchiness. Then it starts to appear in other areas of my body. As an example, I awake at 4am feeling something funny in my mouth, my upper lip was swollen and kinda itchy I continue sleeping and when I got up I looked myself, my lip still swollen but not itchy anymore and after 2 hours it is starting to go down. Now I am at the computer my legs started with little bumps 5-6mm diameter, itchy and slightly red and then I scratch involuntarily and then after 10-15 min more and more start to grow covering a 5" area in average, usually following a symmetrical pattern more or less. Then little by little it becomes very itchy, the bumps start to group converting into huge swollen areas -3-4" red, hot, burning sensation that last for 30min or so and then start to decrease an disappear. This happen all day long. Later it can be my arms, my chest, neck, face, scalp, my back, abdomen, bikini area, my hands (dorsal, palmar, my finger(s) become(s) completely swollen). It is very uncomfortable. I am not expose to the sun. I don't go to the beach. I didn't change diet, laundry detergent or other that I can think about. The only antecedent that I don't know if it is related with this is that I went to the pool a month ago and as usual I apply moisturizer in my legs because I know I am allergic to chlorine (I use to get allergic reaction to chlorine in my legs that last for several days). Other than that I know I am very allergic to mosquito bites but just bumps of 1" diameter as maximum that disappears and that's all. I was looking for mosquitoes inside my apartment but I don't see them unless they are so small that I can't see them. Until now I have been controlling this with antihistamines, anti itchy lotions.This happens indoors or outdoors. Another symptom that I don't know if it is related is that 2 weeks ago I started with burning sensation in my esophagus and epygastrio and sensation that my food stocked in the esophagus mostly at night fcy:every other day.
The symptoms are suggestive of hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.
Many cases of hives are "idiopathic," meaning no cause is known. Others may be triggered by viral infections or medications. The mainstay of treatment of hives is antihistamine which may be necessary for prolonged periods (in excess of 6 weeks). Short courses of oral cortisone or steroids are taken for short periods (one to three days) to settle more severe symptoms. You may take Vitamin C along with the prescribed treatment. Vitamin C is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine.
