Hi I’m 59 had a Medtronic pain pump implanted 4 years ago It was the best thing I ever did recovery wasn’t bad I had to wear a back brace with extra padding on my hip for about 3 months to keep the pump in place to form a pocket I started off with Morphine but made me nauseous than Dilaudid now I have a mix of Dilaudid and Bupivacaine is what works best for my leg pain. If I’m in more pain then I go get it adjusted.
I hope your son finds some relief.
