I knackered the my tendons and cartilage in my knees two years ago. The culmination of doing a lot of walking over the years, particularly that summer (2019) as I spent a fortnight in Cornwall walking the south west coastal path during the two weeks. I'm not getting any younger, I was 60 at the time. Dr referred me to the hospital for physio, but they were unable to offer me any due to the start of lockdown, so I tried tumeric tablets, mixed with black pepper, after a friend recommend them as he had the same through jogging after many years. I bought them online on Ebay and they definitely helped me a lot.
