How much pain is normal with gallstones?

Okay so over the weekend i was in hospital with sever chest stomach and back pains. The pains were like I was wearing an extremely tight bra, and were constant but dull. The docotrs in the emergency ward told me i had gastric reflux, and sent me home with pain relief and an order to see my doctor. I saw my gp, and got an ultrasound done, turns out I have several gallstones, and they are rather large. We aren't quite sure what they are made of just yet, but i'm thinking cholesterol. I'm still in quite a lot of pain, though mostly in my upper abdomen, which feels slightly hard to the touch. It's worse first thing in the morning, and makes it hard to sleep at night. The doctor also said that there is no sign of a blockage or infection in my gallbladder either. My question is, how much pain is normal with gallstones, what can I take to relieve the pain, and does it sound liek i may have a bloakcge that needs to be checked out?
