I have nodal osteoarthritis, so am used to lumps on my fingers. However, I have now noticed a similar hard,bony lump on the front of my knee, just below the kneecap. I've looked through some of your information pages, but they only seem to mention nodes on the fingers. Do you know if they occur on the knee as well, please? Although you can't hear creaking when I move my knee, I can feel clicks if I put my fingers on it while moving it, so I suspect that it the arthritis may be in the knee as well as fingers (and spine). The bump is not painful most of the time, unless I press or kneel on it, though my knee gets very stiff if I stand or walk for a long time.
(I will go to se my GP - when I can get an appointment - but he doesn't seem to know a huge amount about nodal arthritis unfortunately.)
PS Do you know when the new Wrexham support group will be having its next mtg please - I went to the first one, but had to leave early to get my son from school, so I didn't hear when the next one would be. Thanks
