Suggest Treatment For Fluctuating BP Levels

I have Parkinson s disease and have been taking Mirape, Stalevo 200 and Amantadine. my symptoms were pretty much controlled until I fell a year ago breaking my hip. After surgery for hip replacement, I had to have a second surgery due to failure of the first replacement. I have recovered from the effect of the surgery but have experienced a number of health problems since the surgery. I have had several back problems that have been treated by pain care physicians . I still have some pain in my lower back. My greater problem is my blood pressure which fluctuates from 185/104 to 85/54 and my feet are both excessively swollen and my movement is terribly affected (these are recent developments). I have been freezing up, have difficulty turning over in bed and my tremor is much worse. I have taken Mirapex (1 mg 4 X day) for several years; have been taking Stalevo 150 for several years but less time than the Mirapex. I was taking Stalevo 150 (4 X day) but changed to the 200 during the past few months (4Xday); The Amantadine was added in January of this year(twice a day). Can you help me?
