Before you read any further, I want to make it clear this is NOT an attack on pharmaceuticals. A phenomenal amount of work and research goes into ensuring they are safe and fit for purpose.
Nearly everybody has taken a course of over the counter or prescribed NSAIDs (Non-Steroidal Anti-Inflammatories) at some point. Drugs like Ibuprofen, Aspirin, and Diclofenac are used to reduce inflammation following an injury. They are very effective when you have tweaked a muscle in your back or had a bump.
They work by interrupting a chemical chain of events that occurs when tissues get damaged, preventing the release of prostaglandins. However, this is a relatively unspecific mechanism and its effects are still being understood.
One sinister effect that is being investigated is the link between NSAIDs and stroke.
Worth checking out before taking an extended course.
Better to treat the cause of the problem.
