I am female aged 83. I have suffered central lower abdominal pain for 2 years. I wake quite happy in the morning but as soon as I take anything by mouth, even water, I start having these pains. Sometimes they are a constant pain, other times they are spasmodic and more severe and seem to be related to a lower back pain. I have had two CT scans and an ultrasound scan without any result. I am being monitored for low-grade lymphoma which does not seem to cause the haematologist too much concern. Previous history:- 2 children 1953, 1956, hysterectomy 1958, ovectomy 1960, gall bladder removal 1985. Can anybody advise?
