iheartcats Posted March 15, 2009 Report Share Posted March 15, 2009 I'm still getting some hives from stress and heat (showers) and a few flare-ups here and there even with Zyrtec and Zantac. Granted, I've been on Zantac one day so maybe that's not enough time for it to really kick in.I do have allergies, but they'd rarely caused hives before POTS. Now I get the hives frequently, even from non-allergenic causes (Stress/Emotional Situations and Heat/Hot Water/Showers).Is this something underlying with the immune system, thus POTS? I can't wait until I'm able to try allergy shots to see if they help, but even my allergist doesn't think they'll help the heat/stress hives as thsee are really non-allergenic sources, which I don't understand. Thanks for any help...this is distressing! Quote Link to comment Share on other sites More sharing options...
