I'm at my wits' end.

I don't know what to do. 15 months ago I had a total knee replacement. I had been told to put it off as long as possible, but it finally got so bad that I had to have it done. I had my pre-op day and then had to wait so long for a date for the op that the three months following the pre-op day had almost elapsed and I would have had to have another one. I had always seen the top consultant in the hospital and was very happy with him, but it was suggested to me that if another consultant did the op, I wouldn't have to start all over again with another pre-op day, so I agreed for the op to be done by another consultant. From day 1 after the op I knew things weren't right and I told the consultant so on my first appointment after the op. I had sever groin pain on the same side as the knee replacement and something told me that this wasn't right. I was told it was early days and to wait and things should improve. That was the only time I saw the consultant following the op. Since then I have had several more follow-ups and mentioned the groin pain and the pain which has now developed in the other knee because I am walking in a way which puts a strain on it - this knee was fine before. It was suggested that the groin pain might be referred pain from my hip and that maybe I should have an injection in my groin which, if the pain went away, would show that it was referred pain from my hip. I knew that my hip was fine as I had asked another consultant, whom I see regularly for osteoporosis, (which, I am glad to say has now been cured by a wonder drug), to have a look at my hip x-ray and she said it looked perfectly fine to her. Trouble was, I couldn't really tell the knee doctor that she had said this! Two days ago, after the groin pain had been getting progressively worse, I stood up and my knee just seized up completely. I got my GP to refer me to the hospital yesterday and saw two more doctors I hadn't seen before who told me to rest with my foot up and have a scan in 5 weeks time! This scan was supposed to have been done last week on my previous visit but for some reason, it wasn't. I am in quite severe pain and can barely walk, but, the groin pain has gone! I now have a non-functioning leg and am in pain and my other knee feels as if it is going to collapse too, due to the strain it is under. I do have a life and I can't sit round with my foot up for five weeks just for the scan and then more time to have the results looked at. I don't know what else I can do. Sorry for such a long post, but if anyone has any ideas, I would be very glad! I just don't seem to be any closer to getting it sorted out in spite of all my visits to the hospital.
