I went to Arrowhead Health Centers - Scottsdale about a year ago with knee problems. The Doctors and Therapists worked with me and relieved the pain. Last fall the pain started again. Not as severe as before I visited Arrowhead. I returned to Arrowhead for more injections and therapy. I am amazed at the effect they have had on my life. Before I went to Arrowhead Health Centers, I occasionally had to use a cane to aid me in walking. I have not used a cane in over a year. I am in the gym 4 to 6 times a week and my knees are no bother in the slightest. I highly recommend Arrowhead Health Centers. Especially the Scottsdale facility.
