Zantac as a H2 blocker

So today I went to the Physiotherapist who was shocked by the severity of the hives I am experiencing but had heard of it, although she thought it was related to body temperature being affected by hormonal fluctuation. Nonetheless, not interested in a diagnosis as yet, as I will be seeing my GP when I can and recall all of this to him and asking for a blood work-up.

After the Physiotherapist I went to the Chemist and purchased Zantac. I popped one as soon as I was back in my car and had my bottle of cold water in hand. Nothing miraculous happened, but a definite sense of relief came through within an hour. In particular the palms of my hands, my cheeks and jaw line, legs below the knee, and torso, all calmed down. Hives were still visually present but the need to itch had subsided.

Following the instructions not to take more than 2 tablets in a 24 hour period I have taken another this evening, and the same itching areas remain limited and continue to subside. My forehead too seems somewhat relieved, although a horrible rash where they have all joined up from scratching is present. What remains bad for me are my thighs, uppers arms and elbows, all with a mix of aged and new hives. I'd estimate I am having new outbreaks up to 4 times a day, but right now I think they are limited to what came on earlier than 6 hours ago,

I am also taking my once-a-day anti-histamine, Fenofex, twice daily now in alignment with the Zantac, but I more firmly credit any relief to Zantac as a H2 blocker because of the improvement this morning.

My period didn't return overnight, so hopefully the 35-ED is taking control of that situation, but more so I want the hives gone as I plan to look for a new job and do not want to be chronically affected by hives if I attend an interview. Fingers crossed also that the hives do not return next month.
