Hi just feel I need to write this done might help. I am due to have a knee replacement in January and getting so scared already. I know I need it done bone on bone and very painful but anxiety going through the roof.I'm even scared of the tests before surgery and so angry with myself. I have a root canal infection at the moment and on antibiotics so that's not helping, but just wish I could get a grip,as you all know having H.A is the pits, wish there was a magic cure. Thanks for reading take care
