HElp!!!!

"LAP BAND" Question....well its been 6 1/2 months since my surgery and im @ 154 from 215/220. Im so happy. But there is a question i want to ask you, i was wondering if it happens to you as well. You see i havnt been working out and im now at the stage were i want to build some muscle but when i exercise with the "ball" i have major pains on my area were the lap band is. You see it its still feels like a hard small ball inside of me. But the point here is that i hurt if i work out. So maybe i thought u might know why or if it happens to you???? Can u help? lol..... I just hate calling the Doctor . God Bless Ismary
