I had the posterior lumbar interbody fusion surgery L5/S1 February 7. I have been doing really good 2 weeks ago I was having my yearly exam and I was getting off the exam table and my foot slipped and I almost did the splits. Since then my back has been sore as if I pulled a muscle so I have just been taking it easy. For the last couple of days my pain seems to be getting worse. I am experiencing a dull achy on going pain in my lower back and today I am hurting what feels like on my spine whether I am standing or laying regardless if I take my pain meds or muscle relaxers. I am not sure what is going on. Has anyone else had these pains?
