Hi, Welcome to Health care magic forum.
As you describe, it appears to be the utricaria, and it is due to the
allergy, to some thing, like food, clothes, cosmetics,etc which is started recently.
I advise you to consult a physician for diagnosis and treatment .
I usually prescribe to my patient with such symptoms levocitizine, montelekast,
albendazole, and
ofloxacin.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have good resistance.
Wishing for a quick and complete recovery. Thank you.
