I had my spinal fusion on Jan. 25 of this year. Walking is a great way to strengthen things. I'm currently doing water PT and land PT, and I will admit being in the warm water pool is lovely and great exercise. The therapists have me walking back and forth in the water, and then doing leg stretches. Sometimes, local gyms have an arthritis program that is pretty inexpensive. The Arthritis foundation has listings of places.
I also had a spinal fusion L4-L5, only 3 months ago. I still have pain and a lot of stiffness. a hot tub will help, walking is what they say is best, write, lets share experiences and help each other.
planing a trip to WA this August, moving in a year or so to the port angeles area, do you know the area??
