Hives

I've had this since I was a teenager. Im 61 now. When I was younger the hives might appear in different places on my body.
For the past 10 years 95% of the time they appear on my feet.
I've been to several Drs and had diagnosis from peanut butter, chocolate, antiinflammatories meds.
I went a year without taking a single nsad.
Still had hives.
Anyone know something about this.
