Talking about trapped gas, that's what I get. I have started doing the stretch that heather recommends and it makes me belch like you wouldn't believe. Then my tummy feels so much better. It happened yesterday. I was in the car for over 4 hours on and off and my guts just did a number on me. I had to go to a concert last night. My tummy was huge and I felt awful. So I lay on the floor on my side, bent knees and take one arm and lift it up then try to get it to the floor, so now you are lying almost flat but with your knees bent to one side. It takes time for that arm to get to the floor and all the time I belch and belch. This stretch by the way I also did when i had a frozen shoulder (my physio man got me to do it). Anyway, try it it will help, I am sure. Neeta
