Thanks, Sue. I am definitely going to keep looking at causes until I get a better answer. (I tried forearm cane but it placed my wrist in a very uncomfortable position. Wish it had a greater angle so that forearm could bear some weight) . I hate the thought of any kind of walker as that seems like a step backwards (I was off the walker within a week after surgery) but I'll try all options. Am hoping a lift in the left shoe is not the next step as that was a failure several years ago -- made back pains worse. Getting old (80 in 2 days) is sometimes a bummer!! Will see if I get in-person PT visit next!
