I have a torn maniscus in my right knee. To make a long story short it has not been repaired. When I bend and twist the right way, the torn part of the maniscus slips out and locks the joint. Today was the 1st chance I had to clean the boat and of course I had to wedge myself under the race hatch. Upon exiting this small place I had to twist and bend myself.....then all of a sudden that excruciating pain came back. I was stuck in the boat for over an hr. I am now in the house and was able to get my leg straightened out, but can't put pressure on it. So I don't know what pleasantries tomorrow has in store for me!!
