Permanent balance issues and tremors don’t seem likely after a 6 day taper, maybe a rapid cessation of benzos? Certainly a response to a fast taper rather than a very slow, gradual one that is advised. It sounds like you might now be taking clonazepam again so hopefully those issues resolved for you. I had balance issues that I didn’t realize were due to clonazepam until I was off it. No falls in over a year. Good luck on keeping a doctor in the loop with prescribing it for you.
