Update January 2020 ... Unfortunately I am unable to take advantage of Biores in the future as I have an implanted dual chamber pacemaker. For anyone considering bioresonance with David or Chris I would strongly recommend. It's made a massive difference to my life. Previous review - My brief history : Six and a half years with Lyme Disease only medically diagnosed in 2013 and subsequently treated with IV antibiotics and varied medications with very little relief. Anyone who suffers with Lyme Disease will appreciate my situation. I visited David Franklin at Bioresonance in Leeds who conducted a scan, identified evidence of Lyme and multiple co-infections and initiated treatment, I was also recommended to undertake a Parasitic cleanse and daily dosage of apple cider vinegar. Six weeks later I felt a definite improvement. There is a long journey ahead but I feel positive for the future. Many thanks to David and Chris.”
