Chronic Health Conditions Discussion and Support

Get a product from a vitamin shop called Candex, take it at least an hour before or 2.5 hours after any meal. You take it twice a day and it dissolves yeast from your gut. Take probiotics, especially any which contain a strain called Reuteri. This one two will heal your gut and lower food sensitivities.
Also avoid fancy salid especially bagged stuff. This stuff harbors yeast.
Those things cleared my hives years ago.
You can treat the welts w coconut oil vitamin c powder w some drops of oregano oil mixed together and the rubbed into the hives.
Good luck.
Benadryl is dangerous please avoid its associated w dementia.

Also the "bites" are related to dust mites. I advise getting mattress cover & covers for your pillows. And thoroughly clean your bed linens. Couch and fabric chairs will be tougher. There are enzyme products to put into your wash to clear the mites.
That was final step that helped Me, a medical resident advised me about the mites.
Hydrocortisone is better while you're itching than any Benadryl but don't take for too long.
