I have internal bleeding in my right knee which has been going on for 3 months. I am a 59 year old male living in England and have suffered from rheumatoid arthritis since the age of 21.I have no other health problems. Despite many aspirations (sometimes using compression bandages,) the bleeding will not stop. It is so painfull that I have not been able to walk more than a few steps for months. I have been to see haematology specialists, rheumatology consultants,orthapedic surgeons (who have perfomed arthroscopies ) and nobody has ever seen a knee (that has has got some damage due to r/a), continue to bleed. I have now agreed with the surgeon to have a replacement knee but he still cannot assure me that this will stop the bleeding. Has anyone out there any ideas on where the blood is coming from and how to make it stop?
