nearly 2 weeks out and still in significant pain

I was about to say maybe you're overdoing it with 2miles a day, but since you've had your gallbladder out, that's probably it.  Did you happen to have a hernia repair with it?   That HURTS and takes a while to heal.  Just try and not overdo and take the darn pain meds if you have to.

I told my doctor I was walking 2 miles, he was really happy... But I'm not sure it was best for me.  And oh, yeah... I'm walking with my dogs - a 130lb mastiff and a 30 lb corgi - so that doesn't help ;)

I just had the gallbladder, no hernia.
