Let me first of all say that I have just sent for some PP, so I’ve yet to try it. I have EDS, ME/CFS, POTS and whole body neuropathic pain(which is related to these conditions and is not idiopathic) and possibly MCAS and or HI. I am having such a rotten time at the moment with GI issues and food/drug sensitivities, that I had to do something as my doctors are pretty clueless.
I tried the H1 and H2 meds to trial for two weeks to see if I have MCAS/HI and after four days have been so ill, I had to stop. I feel so sick and fluey and my GI is going nuts. I will be trying the PP very soon and I hope it works for you and me. Hopefully someone will be able to advise, as obviously I cannot, but your diagnoses sort of clicked with me!
Good luck and I hope in the longer term you find some relief.
