I had the same problem. I left my Dr office after a 1cc fill. It takes me 2 hours to get home. Half way home, I started burping up foamy saliva, lots of it. I called the Dr, and he had me return immediately, and he took .5cc out. I am still having problems keeping fluids down, and have lost about 10 pounds in 4 days. He is out of town for the long weekend, but I think I need to have some more removed. I was hoping it was just irritated and swollen. If you can't keep saliva down, I would be concerned about getting dehydrated
