Dezb,you do get that on the NHS.I went into A+E on the Sunday morning with a really swollen knee which I thought was just fluid,they had a look at it and Xrayd it.Was asked to come back on the Monday to get it drained but there was no fluid in it so was told needed an MRI scan which I got on the Wednesday.Found torn miniscus and general wear and tear and was operated on the Thursday morning and out the same day.Maybe I was lucky but I wouldnt go slating the NHS,it is free after all
