What is myalgia and how is it treated?

Myalgia is the medical term for muscle aches. Myalgia can be localized to one muscle, a group of muscles or aching all over. The treatment of myalgia depends on the underlying cause. For a simple muscle strain, start with the RICE rule:
•    Rest the injured muscle (and take a temporary break from sports activities).  
•    Ice the injured area to reduce swelling.  
•    Compress the muscle with an elastic bandage.  
•    Elevate the injured area. 
You can add over-the-counter oral acetaminophen and topical diclofenac gel to the affected area. For diffuse muscle pain, an oral pain reliever will provide more help.
