Sorry I am not able to provide an answer as to how to stop the itchy, bumpy rash/hives from reoccurring @puravidaville

From personal experience if you want relief from agonizing itching, I highly recommend taking a warm bath into which you add a cup of distilled vinegar. Another thing that helped stop the itchiness was to put Epsom salt on a wet washcloth and rub it over the itchy bumps till the salt disolved -- also while in the bathtub. You can repeat the vinegar baths and Epsom salt, several times a day. I had a nasty case of poison oak in June that took over a month before it fully went away. Clobetasol Prop Ointment was prescribed as I wasn't a candidate to have a steroid shot due to side effects. Please let me know if this helps!🛀🧴

My first guess is that the hives might be a weird undocumented side effect that occurs after you take certain medications that don't mix well in your system. An endocrinologist might be able to help.

You're a terrific husband to seek help from the community @dandays Good luck!
