Hi I just had my gallbladder removed yesterday, and Now I'm in quite a bit of pain, however I also feel really sick like I have both the common cold and stomach flu. I also feel lightheaded, and weak in my limbs, and it takes me five minutes to empty my bladder. Is some of this normal? Also I was taking pain meds but they started to make my heart race, and I felt even more jittery so I had to stop them.
