I have had years of problems with my heart for years, arrhythmias and chest pain. It grew worse and I had to be medicated for arrhythmias 3 times per day. After the removal of a root canal that had been bothering me, I felt immediately better, more energy, and like I had been relieved of a “thorn in the flesh”, so to speak. Now, 4 weeks after healing of the area, I am feeling much less fatigued and am only having to take my heart arrhythmia medication on an as need basis. My heart feels like it is rebounding form a “downhill” course.
