<s>[INST] Hi, I have been to the doctors today. Given antibiotics for my chest infection. She is referring me to haemotology (urgent). Apparantly I was diagnosed with Christmas Disease in 2012 it says on the doctors pc. I was never told tho. I really dont feel that well. Just taken my diclofenac and Zapain. I have noticed spotting on my feet. I had Idiopathic thrombycitopenia P in 1994. I am scared it may be back.. Could this be anything else? Been sweating loads, out of breath. Chest pain..Generally weakness. [/INST] Hello! Welcome to Chat Doctor. Thanks for your query. Since a diagnosis of Christmas disease was made that is a blood clotting disorder caused by a mutation of the factor IX gene, leading to a deficiency of factor IX. There is a greater propensity to develop hemorrhage and the treatment is by intravenous infusion of factor IX. Factor IX has a longer half life than factor VIII (deficient in hemophilia A) and as such factor IX can be transfused less frequently. The symptoms of sweating, out of breath, chest pain are most probably due to the underlying Christmas disease which has caused high metabolic state and weakness. Ill advice you to stop medications no own without proper consultation with a hematologist because for instance the medications you had taken (that is diclofenac, paracetamol and codeine) can worsen your condition.  Ill advice you to consult a hematologist for proper line of management of your underlying disease condition. Wish you a good health. Thank you. </s>
