so my symptoms are:

sore spot in the middle of my chest (mid sternum). my chest feels like i have bronchitis all the time. the pain meds (Hydrocodone APAP Solution) seems to take a bit of the edge off, but does not kill all them pain.

also is there anything else i can do to help the pain (besides walking). i walked the other day, and after 4 blocks felt pretty sihtty.

that is so weird to me, because before the opp i could do 45min on the treadmill at 3.8mph and 1.5% grade. now i'm winded and in pain the day after my banding - walking only 4 blocks or so.

Sounds like gas to me. Goodness, give yourself a break! You're just a couple days out of surgery. I walked just around my house for about 5 days after my surgery. I once went to the store, but it was painful! Walking is good, but don't try to push yourself so soon after surgery or it will take it longer to heal (the scars will pull). At least that's been the case for me.

call your Dr right now that could be gas but it could be something more serious considering the amount of exercise you did before. I don't mean to scare you but it could be a pulmonary emboli and that is very dangerous if not treated. Don't wait and insist you see him or go to your PCP right away.
