 [ Symptoms ] my problem is i am always feeling fatigued in the late afternoon and evening as if i am ready to fall asleep [ Disease ] hi it seems that the 7 years old knee injury that you had has not healed completely till date it may have been a ligament injury and such injuries if not treated adequately at that stage will give lifelong problems the knee seems to have accumulated fluid now effusion it will go away by leg elevation compression bandage analgesics fibrinolytic and anti inflammatory tablets local gels with hot fomentation will help even if it heals i suggest you should get an mri of knee done to prevent any further damage thanks
