What's an Oncology?

It's almost a year since my last post here. It seems an appropriate place to leave some notes as this blog has barely any visitors so feels like a private space even though, potentially at least, anyone could drop by and read these little anecdotes.
I hope I can avoid being overly wordy and curtail any tendency to being maudlin. If you feel I've failed miserably in either of these simple aims then feel free to leave a comment before dashing off to find something more cheerful.
And so to the meat of this particular post...
Approximately 10 years ago, after a holiday in the IoW that consisted of much trekking around that fine coastline, I started having pains in my feet. The pain was, at times, extraordinary enough to cause the need for a walking stick and became so debilitating that I could barely walk the 300 yards from home to the bus stop. I'm sure I must have seen my doctor about it at the time but don't recall any visits until some 6 years later, in 2004. Since then I have MRI scans, X-rays, both NHS and private health examinations and nothing has been positively identified as the cause. Over this period I also started to experience "foggy thinking", memory loss, fatigue, sleep disturbance and, not unnaturally imho, depression. All these symptoms weren't continuous, in fact there were times I felt almost 'normal' . It was just so confounding that I couldn't say exactly what was wrong.
Until today, when the results of my latest blood tests have revealed that I have rheumatoid arthritis and also some kind of liver problem. At last! I'm pleased to have found a name to pin to my condition but the new knowledge of a liver problem and the need to visit Frenchay Hospital's Oncology Dept. is a bit of a concern.
