Hello, I have been diagnosed for facetogenic pain at L4-5 levels in the lower back and due to this I am taking Gabapin sr 600 and tizan 2 mg for the last 3 years or so. However the stiffness has not completely vanished and I find it difficult to stand or sit at one place for more that 10 minutes or so, since thereafter stiffness in Lowe back sets in. I also don't have ankylosing spondylitis. Can you please suggest some low side effect medicine which I can take for a very long period, since I think there is no remedy for this problem except surgery which I am not interested to go for. I also do daily back stretching exercise for some relief.
