The diagnosis for what was causing all my leg pain is Osteoarthritis. This type of arthritis can flare up at any time and go away just as fast. I had some very severe pain days during the month long flare up. Some were not as bad as others. As the appointment approach it stopped.
Last Sunday going into Monday I had one of the most severe pain days. My leg hurt so bad Sunday night that I could not sleep. I went to work and came home hobbled up. It carried into Tuesday with a lower degree of pain. Wednesday was a low pain day but this had happened before, earlier in the month and I was expecting another flare up Thursday. I woke up to nearly no pain on Thursday and had one of my best days in a month. I went into the doctor office on Friday morning with no pain but some slight stinging when I would bend the knee tight.
The doctor, using the earlier x ray, MRI and my description of the symptoms came to the conclusion that I have Osteoarthritis. He told me that it could flare up at any time. In fact the next time it flares up I am to call the nurse and make arrangements to come in immediately for an injection. I have had injections to the knee before and it isn't fun but he says if it is Osteoarthritis I can expect instant relief. So I'll look at as an opportunity to confirm the diagnosis.
I hope the doctor is right. I feel really good right now with zero pain. Attitude is much improved.
