16 days from wedding and allergic reaction all over body! 😫

There's a lot of home remedies such as olive oil, apple cider vinegar

I'm not a doctor, but I do get hives too from various soaps, detergents, cosmetics, lotions, touching literally anything... You should take an antihistamine, like Benadryl. It reduces the hives and relives the itching. If you can stay home for a day, I recommend it. Benadryl makes me so sleepy.

Also take an oatmeal Aveeno bath or a bath with baking soda. Make sure the water is on the cooler side -- not cold, but you don't want it hot. After the bath, take a washrag and soak it in cold water and use it as a compress on the most hive-y parts of your skin.

Wear loose, baggy cotton clothing. Try to keep as cool as possible. Calamine lotion helps with the itching.

If you're still not clearing up in a few days, see a doctor. If you think you've used anything new (soaps, lotions, etc.) or eaten anything new in the past few days, stop using or eating that immediately until you can 100% identify the cause of the hives. It might be that new detergent, but if you used anything else new recently it could be that too.
