Just had MRI for ongoing back pain following fusion l3 and l4 2 years ago. This MRI shows severe compression of nerve root at S1. And mild caudia equina. My PCP thinks conservative treatment but my physiatrist who is giving me injections in spine every three months says to contact neurosurgeon. I called and got an appt for late September. Neurosurgeon did not get copy on MRI. Every thing I read says caudia equina is a medical emergency. Need you thoughts please?.
