<s>[INST] Hi, I am a 35 yr old male and i was diagnosed with pericarditis resulting from a viral infection in aug 2009. I was then placed on an NSAID, naproxen 250mg twice daily which sorted out the problem. However, the pericarditis has re-ocurred about 7 times in the past one year and as a result, i am constantly on naproxen 500mg twice daily. I need to know if this medication is doing my body any harm and also, if i can continue exercising by playing squash. Also, i need to know if there is a permanent cure for the condition and if it can lead to more harmful situations like stroke? [/INST] Hello,You should stay at bed rest as long as you are ill. NSAID is the first choice for pericarditis treatment but when it happens more times (seven times), I would go with another treatment like corticosteroids. There is nothing to do with stroke. You should see your cardiologist for changes in treatment and echocardiography evaluation. You should take rest.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Anila Skenderi </s>
