CDC's website provides health information for your general knowledge.
Concerns about a medical condition--either your own or that of a family member, should always be addressed to your primary care physician for advice and care appropriate to your specific medical needs.
CDC does not recommend self-diagnosis or self-management of health problems that should be attended to by health care professionals.
