My shoulder pain was a lot like having a migraine headache. It was constant and kept me up all night. Dr. Fiel, or as I now refer to him, “Dr. Fiel-Good,” put me at ease and made the injection painless and easy. I now have my quality of life back for the first time in years, free of pain.

It was a very relaxed and down to earth experience in the clinic…the injection was over before I realized it had even begun. Not only can I finally sleep on my shoulder for the first time in 6 months, I am ready to get back to winning some team-ropings!

I just wanted to thank you for your kindness and professionalism when I had my regenerative therapy injections in my hip. It could not have been a better experience. But most of all thank you sooo much for taking my pain away. I am almost 5 weeks post and it gets better every day.
