@hopeful33250. After talking to my GP today I decided to request a second opinion. He is still saying that my pain could be musculo skeletal but I feel that it is too much of a coincidence not to be the Splenic Cyst. I have spoke to my Lymphoma Specialist nurse and she is going to ask for my case to be reviewed by the Multi Disciplinary Team this week and she will phone me Thursday to tell me what they have said. This team consists of Haematologists from both of my 2 local hospitals and a Radiologist, so a second opinion may not be necessary. She mentioned follow up ultra sounds which is the first time that this course of action has been mentioned.
