just a thought, bc this has happened to me:
have you considered your diet?
I have chronic health issues and do not absorb all the nutrients from my food and when I get anemic, I have horrible pain.
Having your b-12, iron and folic acid levels and while your at it uric acid levels is not a bad idea.
If you do not sleep well, I would get checked for fibromyalgia, and or sleep apnea.
Poor circulation is very painful.
One last thing: exercise. Sitting too long can make just about anyone stiff.
Try taking more breaks and doing some stretching. Hope you get if figured out. Pain and quilting are not supposed to go together!
