About a few days ago there appeared a posting from a PD caregiver concerning his father's difficulty in swallowing. About in April or May of 1995 David Robertson posted info here about how he was able to help solve/alleviate his swallowing difficulties. His solution involved applying pressure with his finger tips to the back of his neck, up close to the base of his skull. Seems simple enough and the cost? Maybe it will help your father. Check the PD archives for his complete description for finding the right spot for applying the pressure. It is nice to be back on this network. I missed a lot this summer but am catching up by reading the archives.
