I think it took about a month to really feel like things were on track. But little signs of improvement started popping up that very first week. Most of the MCAS info I started with, including medications and dosages, I found here at this link. When I first read it, it sounded like the doctor there had literally written out my entire medical history and extensive list of symptoms. He also offered a detailed explanation of the condition, the tests to ask the doctor for, medications and diet that could be helpful. I also found it helpful to read this link regarding quercetin being more effective than cromolyn as a mast cell stabilizer.

I would encourage you to keep fighting for answers. I sure hope you find something that helps you feel better soon. 🙂
P.S. It wouldn't let me submit this with links... so I will DM them if it will allow that.
