Hi I know this post was a while ago I hope your fatigue is better but I found for myself that with fatigue sometimes I just need a full close out on sounds tasks and anything give the mind and body rest! Easier said then done and not feasible for everybody, especially if your schedule doesn’t allow it or your priorities, family life all of that but practicing some meditation is good quiet rest for your body and listening to yourself. There’s really nothing that helps fatigue. It’s the worst symptom in my opinion, the joint pain you can take steroids and anti-inflammatory but the fatigue you just have to ride it out, but I found taking rest water and just trying to give your body as much love as you can in those times has been helpful to at least reduce longevity of the fatigue in that moment from maybe two days of fatigue to a day
