I TO HAVE MOUTH PROBLEMS. i have a bed that raises up or down i raise my head and shoulders. my legs then hurt it is a choice i made. legs or mouth. at least i can eat. oxygen helps. lot of times just a swallow of water brings it on. so moms work of fixing a meal goes down the drain well my beagle gets a good meal. MEDS cause i don't know. i just accept it other thing PD causes. i have accepted lot of things i never had or could do so am i wrong to just accept it. i do fight lot of things. that is all the help i can give as of now. wipe tears away and say tomorrow will be better( i hope) I.Y.Q.
