@helenr I would suggest starting with a visit to your doctor for an evaluation. The doctor can also refer you to physical therapy for balance exercises. But, first make sure there is no physical cause. When I was so sick last year, I was sent to PT for balance. @johnbishop recently posted a connection to balance exercises—they’re great. Good luck and I hope your problem gets solved!

Anytime you have an issue that is 'disconcerting' I think it needs evaluation. Who knows you better than you? Listen to your body and what it is telling you. Fractures are more difficult to deal with as we age. Best Wishes
