I had sudden onset of severe back pain Monday. Husband took me to Dr Tues. Got 7 days decreasing prednisone, x-rays clear, blood cell count normal. Improved one day, slightly, but since, pain seems to be moving. Back slightly improved, but now leg involvement, particularly right leg. Having great difficulty bearing weight at this time. needing assistance to walk. Have follow up with Dr - but not for 1 week- next Fri. Am not optimistic. Thoughts?
