you could be experiencing a food allergy. These typically cause red itchy hives to spread all throughout your body for 12-24 hours. If the problems go away, then you're fine, if not, see a dermatologist at your earliest convinence. In the meantime, try using some type of lotion that can provide itching relief since it can be bothersome.
Have you used any new cream , shower gel, different materials in clothing, underwear ? Have you been outside in the sun , near any allergens like cactus plants ?
Thank you to all. Did go for blood work. Allergy gone after 3 weeks!!!! Watchng food intake. Looks like it is some food allergy.
ahaha that'll do it especially sea food or nuts..actually anything that you are sensitive to .what did you eat that last 24 hours before the outbreak ?.
