I did all blood tests, everything is clear. i dont have any allergy, coronavirus or flu. i get low grade fever and body pain and fatigue everyday from 40 days. in the morning i am so good but later around 2pm or evening these symptoms starts.

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health!

Wellness: It would be very hard for us to try to guess about the cause - but glad your testing was normal. Spend time w people even if it is from a distance. Having a support system is important. Work to get at least 8 hours sleep/ night & eat healthfully. Try daily aerobic exercise, acupuncture, tai chi, qi gong, yoga or meditation.
