My flu experience has been tricky. A few days ago, I thought I had fully recovered. However, yesterday things took a turn. Suddenly, my flu symptoms returned, accompanied by body aches. My lower limbs feel as if I've walked for several hours, my joints are hurting, and my muscles are sore. Initially, I worried I might have dengue fever, but it seems to be just a normal flu since I don't have any other symptoms associated with dengue. This realization made me feel relieved and less worried about my condition.
