Hitch

I am noticing lately that my left leg seems to be considerably weaker and harder to balance on/control than the right. This causes me to lose my balance mid-stride and take a few side steps to correct. It also makes rounding corners difficult - I bump into walls - and leaves my gait very halted and uneven. Nurses at the hospital said I have a 'hitch' in my walk as they saw me on the treadmill, my left leg lagging. I am considering purchasing a cane for use around the house.
