When you show symptoms such as a fever, cough, and CRP levels that are too high, it might mean there is a serious infection in your body. The high platelet count may also be a sign of inflammation. It's vital to stick strictly to your doctor's instructions since they are most probably dealing with an infection at the moment. Keep them updated on any shifts in your symptoms, or if you're feeling worse. Rest, drink a lot of water, and take the medications as prescribed. If you see any signs of your symptoms worsening, contact a pulmonologist immediately.
