Pat is everything a physio can be. A nice sadist. He massaged, bent, pushed, pushed even more. I could take it. He said 'no higher than pain level 5'. I am very fortunate, that all tendons and ligaments are fine. It was just the bone/cartilage. My reward for all the torture was his massaging my foot, pushing up past my knee to reduce the swelling, then fit me with a mid-thigh to ankle compression stocking. He also reiterated the need for pain management being key to doing the exercises. So, no more 'toughing it out'.
Message assimilated. :)
