I have found that doing some leg exercises and foot exercises and just generally keep moving, daily, has made me feel stronger. I use a recumbent bike or a portable elliptical daily. I was never offered Physical Therapy by my primary, a neurologist, or the podiatrist. I went from a cane to a walker very quickly. I could not use a cane on pavement. Now that my legs feel stronger, I have asked my primary for a referral to PT for balance and gait training. My hope is to be 'taught' how to safely use a cane outside of the house. Getting a walker into a car is tricky.
Are you presently taking PT? I hope they address your concerns.
