Ten or fifteen years ago, a pharmacist gave me a pharmaceutical paper (lost now) dealing with muscular pain (e.g., back pain)to take the fullest advantage of the NSAID effect of ibuprofen. The paper claimed that taking occasional ibuprofen only masked the pain, whereas taking 2.5-3.0 grams in the course of a day for 4-5 days gives a better chance of allowing the NSAID effect to kick in. Any references and/or recommendations on this?
