I had rotator cuff surgery and got the pump too. They are preprogrammed at the hospital, and difficult to hack.
I wanted to make it last 3 days rather than 2, and had to partially disassemble it to make that happen.
I succeeded, and committed a felony in the process.
Lol. I won’t tell anyone if you don’t.
With modern technology and modern chemistry, it seems that the pharmas could design a pain med that does a much better job instead of relying on a med that has “been with us since the beginning of time.”
The current choice of pain meds don’t do the job and can cause addiction. Two strikes.
