My mother has had PD for about 17 years and has had 2 pallidotomies on the same side. Lately she has been complaining about an inability to get rid of saliva and that it is thicker than usual. She says it is like a rubber band when she tries to swallow it comes right back up and she finds it hard to spit it out. Her Neurologist suggested oral balance which helps with dryness but that doesn't seem to be the problem. Her primary care doctor suggested robitusson cough medicine but again that doesn't seem to be the problem. Has anyone else had these type of symptons? Steve Neumeier
