Went On Carribean cruise in March. On way back to Key West the ship skirted between two storms and the ride got rocky to say the least and Nature called in the middle of the night . Heading back to bed the ship lurched as I was exiting the "office" and I struck lft knee hard enough to put me on the floor in excruciating agony. I have a HIGH pain tolerance and it was BAD. Saw the ships doctor and he said to just take it easy so I cancelled all excurtians that where planned because my knee and lower leg where so swollen they where leaking fluid from my pores. Went to regular Doctor when I came back from vacation Doc took a wait and see stance..It is now July and my leg is getting nothing but worse and I have a downstairs laundry its kills me that I find myself planning when i head down and getting the most out of each trip and have at times had to rest leg for several hours because of the pain. Doctor finally took xrays and guess what its broken and bone fragments are under kneecap grinding into my ligaments..Life is just marvelous..
