Source of pain?

I'm 6 weeks post-op with an unfilled (for now--first fill will happen in two weeks) band. Over the weekend I started having some brief but extremely ntense pain between my breasts...like spasms. So painful I had to sit down. Each spasm only lasted about 5 seconds but they recurred; by Monday I was having several per hour. Nothing was stuck (I follow my postop directives to the letter); the pains occured outside of mealtime. The pain was only between the breasts, not radiating out anywhere else.

Of course I googled "symptoms of a heart attack" and then saw my GP. Based on an examination and my responses to her questions, she ruled out a heart attack and thought it might be irritation from the band. She put me back on Nexium (I think that is what the drug is called in the US); a pill I had been prescribed for one month following the banding. Because she is unfamiliar with the band (I'm her only patient with one) she advised me to see my surgeon.

By Tuesday my symptoms were gone (I had started the Nexium Monday night) and I got in to see my surgeon. He only kept me for 1 minute (but took 100 euros from me for those 60 seconds) and said he thought it was the band moving around (not slipping, but turning) since it was unfilled. He said that once I get my fill it should resolve the problem.

Anyone else experience the type of pain I described above and had it resolve with either medication or a fill?
