PN progression? How can you be sure?
How do you distinguish between symptoms that are signs of your PN beginning to progress and symptoms of other conditions you've had for years; for example, arthritis? I've been dealing with arthritis in my ankles, left knee (the right is a replacement), and hips for many years. The symptoms, particularly late in the day, have always made my legs feel weak, telling me to sit down and take it easy. A year ago, I was diagnosed with idiopathic PN. I don't know if it's large fiber, small fiber, sensory, motor, or a mix (I hope to learn when I next see my neurologist). Gratefully, my only PN symptom so far is balance I can't trust and a wonky way of walking. So far, I have no pain. But toward the end of most days, my legs, particularly my arthritic left knee, will feel weak. How can I tell if this weakness is just more of the weakness I've been feeling for years (in other words, weakness not associated with my PN) or signs that my PN is progressing? Is there a way? Something tells me there may not be a way. (I will as my doctor when I see him next month.)
