I don't fall because I don't do anything that might affect balance. I've had near-falls because of losing focus. Once in the garage while working on a motorbike it toppled over, dragging me down with it. I assumed I have near-falls because of muscle weakness.
Three years ago while jogging I had an inkling of a problem. I was on a dirt road with a steep slope. I'd been on the road for two hours. I kept tilting forward at the hips and wasn't able to stop and stand up straight. While jogging I tilted more and more and eventually fell. I had three falls before quitting. Luckily guys off-roading in a jeep stopped and gave me a ride home.
This " tilting forward" business is still with me and seems to be getting worse. These days I use a treadmill. For the first hour or so I do fine. Then I start tilting forward and have to grab the front bar or the side rails. Then I can continue. The treadmill is in a shed 20 yards from the house. When I'm done and walking back to the house I feel like I need hiking poles to keep myself upright.
Along with the tilting problem my lower back aches constantly. I used to take ibuprofen, 1000mg twice daily. I quit doing that after getting an ulcer. I don't know how this might relate to PD. I don't feel numbness. Just a chronic, nagging ache that gets worse with exercise.
I take Rytary 48mg three times daily. It doesn't seem to affect the lumbar muscle weakness. Could PD be the reason for these 'near-falls'?
Or maybe it's because I'll turn 65 next week?
