I've been on a decreasing dose of pred for GCA and PMR since September last year, now down to 4mg from 60. My rheumy doesn't believe in frequent blood tests. A couple of months ago I went to the GP because I was getting back and joint pain, and he sent me for a blood test. Results I was told showed borderline CRP level but he said there was nothing to worry about. This Monday I had a catheter ablation for SVT. On admission I had a blood test, and when I looked at the result it included CRP, which was flagged at 13. I'm having a lot of back and knee pain I the morning, having to take paracetamol every day. I've also this week had some head pain, but on the left side rather than the right as originally. Not sure whether I should be worried!
