I have been having increased weakness in my abdominal area and lower back, cannot hold both hands out in front of me to wash hands, do dishes or pick up a baby. can pick thing up as long as both hands are not out in front of me. I am also having dull aching pain in left side of back as well as lower back predominately on left side, had an MRI which revealed bulging disks in thoracic spine T9 and T10 as well as lumbar L4 and L5 with some facet degenerative changes in both areas. Mild scoliosis to the left and some mild stenosis in one area. The doctor tells me that she doesn t know whatis causing the weakness, is very hard to function, suggested costisone injections in facet areas thinking maybe pain from them contributing to weakness, am not convinced. any thoughts? Very discouraged, cannot even pick up new grandson. I am 63 years old, female and not overweight at all, have always been an active adult.
