Having recently purchased from PHYX I can only heap praise on the support staff involved at all levels, ive had 5 lower back surgeries, total right and left knee replacement surgery, total left shoulder surgery and im heading for a total right shoulder replacement surgery, i suffer from chronic arthritis in both of my thumbs and at some stage they will require intervention as well, im just starting my journey with PHYX and look forward to moving away from prescribed pain relief medications. Thank you thus far to all the team at PHYX, Regards Paul.
