Thanks for your question. I am Dr Asanghanwa Carlson. I would say pericarditis is an inflammation of the outer layer of the heart. It can be due to an infection and most at times can be caused by a viruses and in this case, the treatment is mostly symptomatic that is giving drugs for the symptoms you feel like pains. It is however a potentially dangerous health n which requires proper follow up. i will advise that you see your attending physician or a cardiologist so proper diagnosis of the pericarditis is made and treated appropriately as it could have other causes like bacteria and fungi. Good Luck
