So around 2007 I had a fall in a shop slipped on some water and straight down on my knee I have had xrays and MRI scan the MRI scan came back as nothing found. Was at my gp today as I had a bad flare up of knee pain to be told that they did find something on my mri all them years ago but weren't completely satisfied with it. So why did they tell me they found nothing if it had off been treated I wouldnt be in pain now. What can I do about this
