I am a sroke survivor who has a buzzing sensation in the left side of my body. It too makes walking etc difficult. I found that if I don't think about what I am feeling or not feeling, and just walk like I remembered I used to, I can walk quite well. I don't know if this makes sense to you, but my Neurologist also said this is a good thing to do. Hope this helps.
I had a stroke in March 2006 that left the right side of my body with zero strength. I gradually regained use of my right arm, hands and leg after 6 months of extensive physical and occupational therapy.I went back to work 2 months after the stroke, even while undergoing therapy. It was about a year after when I felt a sudden weakness in my right arm, hand, leg and foot. Today it has been compounded by stiffness, a feeling that the hand and foot are swollen and a continuous tingling sensation. I also walk unsteadily and have a hard time balancing. I am taking Baclofen but I am not sure if it is helping me. Note that I did not have this feeling during the year that followed my stroke. Could we be experiencing the same thing? I hope that I can help you analyze your condition. I am seeing my neurologist in the weekend. I will post whatever he says that I may feel important to you. Stay strong.
see my post on robotic assisted exercise
lokomat therapy can improve balance, coordination and strength
I work in as an aide in a physical therapy department. I would try any exercise that involves your ankle and strengthing exercises. Standing on mats, trampolines, or a balance board is good for this. Also, try balancing exercises on that one leg such as having someone roll a ball towards you and then you kick it. Stretch bands are good too. be creative!
