"had gallbladder removed on tues. it is sun. went home an hour and a half after surgery. got nucynta. felt invincible. made appointment to get more tests and surgeries same day, went flea marketing, etc. i actually picked up grandkids and wrestled with them, etc. i feel the burn. back hurts. may have torn surgical sites a bit. nucynta made it so i no longer faced extreme stress incontinence, halted my 12 year battle with gerd, cured chronic cough. very good product."
