Hi, I have been told by the rheumy nurse when I asked to have one that .. "they don't tell us much" but I said they tell us more than not looking. I wasn't rude but I was fobbed off. Told it is only when there is preparation for surgery for knee replacement they can. I am not happy as this is cyst is recurrent and makes itself known once hydrocortisone injections to the knee wear off. Humira is slow to work for me and I have just had shot 4. Started mid August. Don't know my ESR etc as no one has let me know my blood results from two weeks ago, and I am not in a hurry to speak to the nurse again. I will chase up results at GP. I know that Humira isn't working enough yet as this inflammation cyst would not be there if inflammation was substantially lowered. It always comes at times of flare etc. I shall pursue the scan via my GP's assistance and use my BUPA (always told never to use it for rheumy as they were so good at seeing you quickly Usually are but obviously I am not getting any scan assistance! The thing is, I am sure my Consultant would agree but the nurse won't let it go further.) Very frustrating when I am so very restricted by it.
