Rejuva Stem Cell Clinic treatment is a simple non-surgical injection into the affected joint with no down time or lengthy recovery. You may maintain your normal lifestyle and allow the cells to create a balanced optimal environment in your joints so your body can repair itself. You should feel maximal results within 10 to 12 weeks at which time you can increase your activity levels to match your comfort, but understand that the regenerative process can continue for long periods of time.
