When you experience high fevers, you can also feel rigors , some shivering associated with muscle tension, mostly upper and lower extremities. It seems that you have been diagnosed with a respiratory infection, and this can certainly be a cause of chest pain, usually pleuritic type, meaning that it gets worse with coughing and deep inspiration. Nevertheless, heart disease can also be a cause of chest pain, and in fact it can present in atypical ways in women, such as indigestion. I believe that you might need to have your chest pain looked into if it persists after your acute infection, particulalrly if you have risk factors for heart disease such as smoking, hypertension, diabetes, elevated cholesterol or strong family history of heart diease.
