Question: Lumbar noncontrast MRI shows L1-2 very slight annular disc bulging, L2-3 asymmetric annular disc bulging, L3-4 prominent asymmetric disc bulge which encroached upon ght left neural foramen resulting in moderate foraminal stenosis and mild bilateral facet joint arthrosis, L4-5 broad based 3 mm disc protrusion posteriorly which elevated the posterior longitudinal ligament but no associated spinal stenosis, with midline sagittal thecal sac diameter of 10 mm, bulging disc encroached upon the inferior aspect of both left and right foramina resulting in mild to moderate right and mild left foraminal stenosis, and L5-S1 shows asymmetrical annual disc bulging. I'm 66 years old, and have been experiencing leg numbness and weakness when I stand, not when I walk. Can you tell me what's going on?

Brief Answer: My reply is below. Detailed Answer: Hi, Thank you for posting your query. I have read your MRI report of limbo-sacral spine (lower back). It shows slipped discs at multiple levels, resulting in pinching of nerves at those levels. These elves travel to the legs from lower back. Therefore, compression of these nerves result in weakness, numbness and pain in the legs. Initial treatment would consist of medications such as pregabalin to relieve pain and physiotherapy (including back extension exercises). You should avoid lifting heavy weights and bending forwards while standing. Some people may aloud require surgery, if the above measure do not help. I hope it helps. Please get back if you require any additional information.

I have pvc's and a few pac's - left pinky finger numb, run over by my car 05 and sharp back pain neck pain - the left pinky thing is new..spinal stenosis as well

I'm worried about the pvc's as they get worse when I lay on my left side, or dont' drink enough water. I've tried med's but they don't work. I am now 47, and I used to get runs of them more than 12 a minute, now perhaps down to seven cause I'm calmer - should I get a full workup
