Muscle Pain
"Previous had this prescribed to me for Back Pain several year ago. 500mg twice a day and it certainly used to take the edge off the pain. Of course it won&#039;t eradicate the pain, it&#039;s only a mild NSAID not an opioid. Recently been using 500mg per day for a week for calf strain from running injury. Really helped in the first 48hrs. It seem there&#039;s a few comments on here regarding allergic reactions. Allergies to aspirin and other NSAID are common. If you are not allergic, then I recommend Naproxin as a starting point."
