I am pretty sure I have Py and am going to be tested for it. I also have major AF and candida, to name a few of many things. My histamine levels are being tested today (suspect high). I wanted to know if any py people have major muscle and joint pain and/or problems losing weight. I have had horrible muscle and joint pain and spasming for nearly 2 decades. I also am overweight and it is nearly impossible to lose it. Thyroid tests are normal, but ND thinks it could be sluggish due to AF. Would love to hear from others with the same issues.
