I am suffering from numbness in the right buttocks down the right leg and my right foot. I had that same numbness plus fairly severe pain from a pinched spinal chord due to spinal narrowing and disc deterioration (overly simple explanation). After spinal surgery the pain and the numbness were totally relieved. About a month ago the numbness reoccurred and seems to be getting worse at times-thankfully no pain yet. Pain management prescribed 150 mg pregabalin daily, advising I probably would have to take it at least a month for any results. Well, the after the first day the numbness noticeably lessened and the mental malaise (from another condition) I have suffered from for over a year greatly improved, all with no side effects! The numbness is still there, and I have gotten used to this level, so I am not sure if it is still working as well as when it was first started. Mentally it has restored my interest in living again! I am due to increase it to 300 mg-hopefully with more benefits. I really am averse to taking a lot of RX medications, but this one has been a god send for me.
