I brought them tendonitis and arthritis. Dr Mike Cronin brings so much experience treating joints -- he's been doing it for so long -- that his prolotherapy and PRP treatments completely cured tendinitis in my upper leg and persistent stiffness and soreness in my neck (from a bike crash). I am so grateful for the help, and enjoyed his straightforward and good-humored approach to all my health and aging issues. Anyone with sore joints or tendons could really benefit from a visit.
