Exercise-Induced Urticaria Treatment

Cholinergic Urticaria (hives due to a sensitivity to heat)

Hello,

I am looking for cures for Cholinergic Urticaria for my son. This condition happened after he was diagnosed with Blastocystis Hominis parasites after a trip to Costa Rica 2 years ago. We finally have gotten rid of the parasite, but the Cholingeric Urticaria still exists.

Diamine oxidase enzymes supplements help with the symptoms, but they are hard to get in Canada. We want a cure.
