I have been experiencing extreme fatigue in the last few weeks. This has been coupled with joint pain in my left fingers/hand/wrist. Ideas?

It could be a lot of. There's no single test to confirm a diagnosis of chronic fatigue syndrome. You may have to undergo a variety of medical tests to rule out other health problems that have similar symptoms. Treatment for chronic fatigue syndrome focuses on symptom relief.Good luck thanks.
Yes, inflammation! You are not describing injury or djd. Inflammation always causes fatigue! see your pcp, or a rheumatolist!
