Body aches
Body aches are a common symptom of the flu. This symptom appears early in the infection but can be misattributed to other factors. The symptom is nonspecific, so if you have recently performed intense physical activity, it is easy to wrongly associate it with the aches. You may feel aches anywhere in your body from your head to your calves.
The aches can be severe [5] and you may need medications to relieve the pain. If you need drugs, over-the-counter medications are fine. You can buy pain relievers like acetaminophen or nonsteroidal anti-inflammatory drugs like ibuprofen. Both work quite well. Endure you do not use more than you need.
