I had l4 l5 fusion 2 years ago. 3 months ago while lifting something very heavy I felt my back give way. I have since without ceasing had mild to sever calf, foot, buttock, and thigh pain. I have had 2 epidurals, emg study, as well as an MRI. There seems to be nothing out of the ordinary other then degenerative disc disease, Has anyone else suffered with this. I am unable to stand, sit or exercise for more than a short period of time without hurting and my calf like it is always about to have a charley horse. Looking for some help!
