I Am Having Spells Of Where I Am Falling. They

I am having spells of where I am falling. they are getting more often now. my hands will jerk and shake and my knees buckle and I then fall. If I get something to hold on to or sit down I'm safe. What could this be? I have Neuropathy but I just had an appt with her and she didn't seem concerned. I've fallen and gotten hurt but so far no broken bones.
