I don't have any experience with the Ambit Pain Control System, but it sounds similar to a nerve block. My nerve block didn't last for 48 hours but it got me in the car and home after an hour ride. After looking it up I saw where most people had it for 3-days and that it uses medications like lidocaine to numb the pain. My question would be would your doctor add any medication and how many days could you use it? I was on dilaudid for about 6-weeks for pain. My doctor also ordered Celebrex, but I couldn't tolerate the side effects. Along with tylenol, 30-days of aspirin, colace, and I added miralax. My husband has started meloxicam and that is working for him! It seems more people can tolerate that.
I would also ask about you being able to get up and walk with it. Would it hook on to your walker? How long is the tubing? I found that if I walked around my family room in the middle of the night it helped with the discomfort. For the first week or 2 most people had to urinate every 2-2 1/2 hours.
Good luck to you! If you decide to go for it let us know how you liked it.
