What Causes Difficulty In Balancing While Having Neuropathy In The Foot?

I am having balance issues when walking and standing still. I also have weakness in the back of my knees. There is a twitching at times, but more concerning is that my knees give out when I’m walking at times. I haven’t fallen yet, but came close to it. My knee just gives out. Sometimes there’s a twitch, but sometimes one if my knees will give out without warning. I do have neuropathy in my feet from type 2 diabetes, but don’t think the imbalance and weak muscles in the back of my knees are related. The weakness can sometime be felt going up the back of my thigh. Any thoughts are appreciated.
