You should call your doctor if:
- You have a high temperature.
- Your chest pain does not get better in a few days.
- You are coughing up bloody sputum.
- You develop a rash, itching, swelling, or stomach pain.
Call your doctor immediately if you begin to have undue difficulty breathing (dyspnea), or your fingernails, toenails, or skin turn dark or bluish (cyanosis). Severe headaches, neck stiffness, or feelings of confusion may be early indications that the infection has spread outside the lungs.
