I had surgery on May 8, 2006, in Mexico. 1st fill July 25, 2006. Have lost 48 pounds. A few days ago, I began to have pb's eating some solids. Like broiled chicken, it goes down and seems to take volumes of air with it. HURTS like the devil. I cannot continue to eat. After 30-40 minutes, the air works it way up. Any ideas? Sheryl
