I agree you need to do therapy for balance.
I am 75 and I can tell my balance is not was good as it used to be. For me I say I wobble. And like the old toy that said they wobble and don’t fall down I might. I have made changes in my home. My kids gave me a stair chair to go up and down to the basement, a ramp in garage and put in walk in tub with handles in and outside the shower. I plan on living here for a long time.
I hope you get some great information as what might be going on and what to do.
