I think we may be at the end of our rope here. My husband has severe central pain (burning butt and legs 24/7). We've tried all the normal meds (though I have to do some research on what doses of each you guys are taking to see if we tried enough of each one). ANYWAY we're now considering a pump. I read some other posts, and there is a lot of talk about relief from spasms but not much I could find about whether it helped with the burning pain (which is the only reason we'd consider it). Any input here?
