In the medical literature, Chronic Pain Syndrome is generally understood to be essentially constant pain that continues for at least 3 to 6 months minimum, without abating, and resulting in additional symptoms other than just the pain itself, such as depression, anxiety and/or extreme fatigue.
So chronic pain fatigue is generally understood to be a symptom of the condition called Chronic Pain Syndrome. Hope that clarifies it a bit for you. But of course only your physician can diagnose what you may or may not have. Best wishes.
Yes mention it. Could be neuropathy. If your diabetic, it could be. But neuropathy does not only happen with diabetes. It might also be poor circulation. Please ask your Dr. Soak your feet with oils, Epson salts etc. Pinterest has suggestions. And they are all natural. Also massage your feet. Hope I was helpful.
Wish I had a professional answer but for me, chronic pain leads to exhaustion and fatigue.
I have neuropathy & I'm not diabetic & my circulation is fine. My Dr says its part of the disease. I take Lyrica. It helps but I also use a stationary bike. It does seem to help my joints also.
