Something similar was happening to me over the last several years. I was having trouble with elbow and shoulder joints, TMJ issues, and fingers were locking into awkward positions. I also had some weird stuff happening with my skin. Some people close to me suggested that knitting was the cause of my troubles, but I refused to believe it!
Several fruitless visits to the Rheumatologist followed. Lupus was what they tested me for the most…four times in two years, and the doc was certain the test would come back positive.
Finally Family Practice doc sent me to a Naturopath, where I was tested for food incompatibilities.
(The individuals who were suspicious of knitting in my life began to cast a dubious eye to my medical care team.) But, based upon blood tests, I was given a list of four foods which I should never eat, and I eliminated them from my diet.
My joints were better in 24 hours. And as long as I don’t go near these ingredients (for me, the forbidden items are almonds, potatoes, soy and citrus) I am 100% pain free, and those skin issues are also completely resolved.
So, perhaps this story might be helpful to you. If there is a naturopath near you who will test for food allergies and incompatibilities, you might find some relief.
