I just went through a bad bout of hives and am slowly on the mend. I see what works for one person doesn't necessarily work for someone else. All of our body chemistry is different. But believe me, I have tried the bulk of all of these. Baking Soda worked well for the itch for a limited amount of time. Oatmeal baths, blah. Aloe Vera with menthol, ahhhh that felt good for a limited amount of time.
I got up several times during the night to apply something for the itch. Prescribed antihistamine did absolutely nothing. I got into some poison oak that got infected then broke out in hives. So don't know if the hives were caused by antibiotic, antihistanmine, or poison oak. I didn't care, just wanted them gone!
I detoxed my body. Fasted for a day, then started taking several vitamins, and ,foods that had natural steroids, like spinach, quinoa, etc, you can look it up on google. Drank water like a fish, and prayed alot.
I am happy to say that I am on the mend. My point in writing this is to tell you to try everything. I am not into synthetic steroids, and I see from some of these articles that they didn't work for people any way.
Good luck, and God Bless You. I feel for those of you that have had this for a long time.
