you have most certainly come to the right place to ask questions and have a moan or two, we all do. Like golitho I can't help with the RF result, but I understand the foot/ankle problem, swollen fingers and aches in the hips. In fact it's the pain in my foot that started me on the right journey.
I had been having back pain for many years, which I put down to getting older (only 53 though) having had children, horm, running etc. Therefore I didn't really do anything other than see my GP. Then the pain the ankle became 24/7 and I haven't worn an enclosed shoe for near 2 years. Swollen fingers and many other little things. I asked to see a specialist and thankfully came across one that instantly knew what the problem was and started all tests, x-rays etc leading to being told I have Ankylosing Spondylitis. You really need a good rheumy to speak to and explain all the things you have wrong with you. Something is clearly not quite right....
