Hello once again to all you wonderful people.. Everytime I have needed help with managing my mom"s Parkinson's, you people have been a wealth of information. My mom is now in year six, and because of what I learned from you, is now seen by a movement disorder specialist. Well, she is doing fine: except for an ever increasing difficulty with sleeping. She can only get 2 to 3 hours at a time, often wth a significant interval between the short "naps". This is making her tired during the day. She complains of aching, and states that the aching is keeping her from sleeping. Is this aching a symptom of te disease, or could this be something like arthritis? Also, can one take sleeping pills when taking the Parkinson medication? Any and all responses will be appreciated. God Bless...
