Can you tell me what is causing my body aches and my tingling and burning sensations on my back? It's been three years. I have seen doctors and had many lab tests and MRIs, and they were all pretty normal except for a few issues with my discs.
Is there a lab test for polymyalgia rheumatica? What can I do to figure out the source of my pain, burning, and stiffness?
Have you had small fiber neuropathy explored? It's a problem with the unmyelinated nerves that some doctors may not know about. Some of your symptoms sound like that. I'm not about there being a test for polymyalgia rheumatica, but that's definitely something you should speak to your doctor about if you're concerned about it. The pain could also be some kind of neuralgia (nerve pain) related to your disc issues. Again, you'll want to ask your doctor for further evaluation.
