Had an L5/L4 microsdiscectomy and am about 6-7 months post op. I am finding I am tender and sore when I push on other vertebrae's in the middle of my back. Is this normal? Is this from not bending enough in the recovery process? I am concerned I am not doing enough bending at this point in the recovery process. I tend to still keep a very straight back and don't bend at all. I know I should keep good posture through out my life but don't want to do some long term damage by not doing enough. Thoughts?
