@WoolspinnerEm very sorry to read about your pain. You mention that you have not been offered blood testing. Is it something you would be able to fund for yourself?
Things are different for me as I have type 1, however, I find high blood sugars will emphasise any aches, pains, sniffs cough, etc.
If you know what your blood sugars are doing, you may be able to bring them down through diet, etc. This could reduce some of the pain you are currently feeling.
I am sure there are some people with t2 who will be willing to advise on which meters best to purchase
