Re: Does Osteoarthritis cause Fatigue?
Hi, yes, it can definitely cause fatigue. The pain itself can be exhausting and when you're in pain, it's very hard to do things physically so your body feels drained, sometimes by the simplest tasks. If you have pain at night while trying to sleep, it will cause you to not get enough restful sleep, which can also contribute to fatigue; I have also read there can be some inflammation with OA and that can cause fatigue as well. Plus if you're just overdoing things that will tire you out and if you get depressed over the pain, that can also contribute to fatigue. So there are lots of things can cause fatigue with OA.
For example: Just think of if you do some sort of exercise you've never done before and you do a bit of it at one time. Like say, leg presses. Usually the following day you will have alot of muscle pain/achiness. With OA, you have pain and stiffness and alot of extra pressure on your spine from the degeneration. This causes problems moving around and walking; When you walk, you might walk differently, with a limp, or using a different posture than normal....all of this can put extra work on your muscles without even doing much. Then your legs feel tired and/or very achy after doing things b/c there is more stress on your legs so your muscles are working harder.
I hope this helps you to understand somewhat...
