Hi. I have just found this thread. I am living in England. I have a history of NHL - diagnosed 2000. Two years ago I started with abdominal pain, gas and bloating, and opening my bowels during the night. An ultrasound revealed a slightly enlarged spleen that my haematologist wasn't worried about. My GP diagnosed IBS. A pain developed in my left side in May this year. I thought I had pulled a muscle. In August when I had my annual checkup my new GP decided I needed more tests. I have seen a lower gi specialist and an ultrasound showed a1cm cyst on my spleen and enlarged liver. My haematologist says that lymphoma cysts in the spleen are not visible on an ultrasound. He has ordered a CT scan and I see a Gastroenterologist next week. I have had to push all the medical professionals to get to this stage.
