Your health care provider will be able to run lab tests to see if you have MRSA. If you have an infection on the skin, your doctor will take a culture from the infected area. Depending on your symptoms, your doctor might test also your blood, urine, or sputum (saliva).
MRSA could be treated by certain antibiotics. Although lot of antibiotics are resistant to MRSA, but which is susceptible would be Clindamycin by oral.
If MRSA is not treated immediately, you could end up in emergency room and they will do IV on you. It is better to go to physician and get antibiotics as soon as possible for MRSA. IV is just a faster way to inject medicine in your body, but IV is only done in emergency rooms.
