The best laid plans

There I was, wondering where to go next - well I've a rough idea, actually, as I've only been to Africa once and that was with a tour group, so I was beginning to play with plans to go on my own. To mull over which country to visit, taking on board general thoughts about safety and ease of travel etc. (For anyone wandering the same path, the Lonely Planet Thorn Tree forum is wonderful.)
   And then, as I woke one morning with the screech of exotic birds and roar of lions in my dreams - I turned over - and knackered my knee. (Knackered, you will appreciate, is a generic medical term for doing something extremely painful but you don't know what.) It is, now, funny - but last week I struggled with the 'How did you damage your knee?' questions, kindly though they were. It took time before I could stand apart from myself and watch me coming downstairs on my bottom, walking into town clinging to the railings, and almost giving up when faced with the step onto the bus - and see that this might be a bit comic.
    But time passed, I grumbled, took painkillers, the pain eased after a few days and I look back at that discomfort in disbelief that it was quite that painful. In fact recovery was so swift that, within four days, I danced the night away at a wedding - and wasn't even stiff the next morning.
    Which should be the end of it? Except that I know I have arthritis in my knees - I had arthroscopies on both knees about ten years ago (it's like a D and C of the knees) and have been warned that the day will come when I'll need more surgery.
   But I want to go to Africa. Last week, I could not have carried a rucksack. I could not have walked the corridors to the boarding gate at the airport. I could not have curled into a seat on a plane for a long flight and ever uncurled again. This week, I can sing, dance, and generally prance about like a puppy.
   So - what to do? If I go to the doctor, get into the system - the referral to specialists and the whole waiting-game - it means the whole knee-thing will take over for a while and travelling go on the back burner until it's sorted. Which could take months. Doesn't sound too inviting to me. The alternative - live for today. Go anyway, and hope I don't turn over in bed and have spend a few days days hobbling somewhere hot.
   It's a close call - what would you do?
