I had all those symptoms, along with lung cancer and when they removed my left lung they told me that I had emphysema.
After ending up in the hospital three times in the last 6 months, for heart arrhythmia and severe joint pain, it ended up I had high histsmines that was causing everything, even the arrhythmia, lung inflamation and cancer.
I took two DAO enzyme tablets that naturally degrade histamine in the body and woke up in the morning feeling 30 years younger.
Within 8 hours all the inflamation in my body was gone, so was the joint pain and shortness of breath. Most astonishing, the brain fog was totally gone.
I figured it out by researching with my phone while in the hospital ER. Ordered the enzyme from Amazon while still in the hospital.
I was amazed that none of the Dr’s were familiar with it.
I've never heard of DAO enzyme tablets, or histamine intolerance. How does one know if they have high histamine levels in their body?
