My husband has mrsa. it was misdiagnosed for well over 2 years. he is having some serious symptoms of unexplained pain.is ther any relationship?

Pain where?: Mrsa stats as skin infection that can spread internally. It needs to be treated with appropriate antibiotics and preventive measure to prevent recurrences. It may best to see infectious disease specialist to look for underlying problems with appropriate tests.

Not likely: You are not diagnosed with mrsa, per se. Mrsa is a bacteria, it is not even really a disease. People with chronic illness and even hospital personnel may be colonized with it, meaning it is growing on their body but not causing illness. At times one can get an infection with this germ. This can be pneumonia, or involve skin etc. It is treated with antibiotics. Active disease wouldn't last 2 yrs.

Nasal MRSA colonized: It is not uncommon for MRSA to colonize the nasal passages, especially after a hospitalization. If it is limited to the nares a topical antibiotic may be effective. Check with your physician.
