[|Human|] I have had 2 lower back surgeries, the first was a laminectomy in 1987, the second was a fusion of l/4-5 in 2002. I never really recovered from the 2nd one. I have an 8 in scar with a plate, 4 screws, 2 rods and a cage packed with bone. I am 51 yrs old. I have had progressive weakness in my legs and back ever since. I recently developed numbness in the saddle area. I had ab showing a slight bulge a c3-4 a herniation at l3-4 and another at l5-s1. they said their isn t anything showing that would cause the saddle numbness. What should I do next? I know this isn t normal and I shouldn t have to live this way.
[|AI|]  Hello Thank you for trusting Chat Doctor common reason for saddle paresthesia to occur is group compression of the lumbar and sacral nerve roots in the lower back, due to some structural abnormality, such as a herniated disc, osteoarthritic process, vertebral slippage condition, atypical spinal curvature or congenitally-narrowed central vertebral canal space. Similar symptoms result in other possible causerie spinal canal stenosis in neck and thoracic region, psychogenic ischemia of nerve roots in lumbar region. Sometimes local nerve compression by tumors, and cysts cause these symptoms. Saddle numbness is non neglectable symptom once again consult your doctor. Till that time take tab. Pregame m twice a day.
