Yes, has to do with my bp. But in an unexpected twist of fate, in my continuing effort to lower my bp, I took a substance (cinnamon bark oil) in the wrong way (in a sugar cube instead of in a capsule). This led to my lungs becoming irritated and losing its ability to expel phlegm. Developed COPD in the form of bronchitis. Realized too late the lower spO2 levels was something to take more seriously. This condition cascaded into my heart failure last year. The heart was effected, so was my nervous system as I developed ataxia, which is about the same thing as Parkinson's. Heart and lungs fully recovered now, with an improven nervous system but crossing my fingers my neurons did not die but only time will tell.
