I can't really add anything to the above, except maybe see your doctor so it's at least noted that you are having balance problems. It maybe something they can help with?

I would ask for a MRI. I took care of my Dad for 10 years and they said he had a busted vertabrae when in fact he had MS, two ways to find out MRI and a spinal tap. When my symptoms started thats the fist test I asked for.

I agree with Dadstater. I would call the Dr and explain what is going on as well, maybe they could get you in sooner.
Hugs and prayers

There is nothing wrong with using a cane or walking stick, there is a lot wrong with falling, losing your balance. anything that will help
