I started having problems with my back over 15 yrs. ago. In May 2002 I had a Interior/Posterior fusion in my lower back. I went back to work full time in July 2003. Been doing really good till late 2011. I have had injects several times and they helped for a while. In May 2012 I had to have another single fusion just on top of the old fusion. Then in September 2012 Dr. Kamson went in and removed scar tissue that had grown over the old fusion. I was having lots of pain with every step and did not sleep well. After having the scar tissue removed I have not needed any pain medication.I went back to work the next day:). Dr.Kamson and all the Staff atThe Spine Institute Northwest have been great. I would and have recommend Dr. Kamson and his team to family and friends. Thank you.
