Ask yourself:

  • Is this reaction a side effect of drugs I am taking?
  • Did I eat anything different in the last few days?
  • Have I used any new or unusual cosmetics or other personal care items?
  • Could my symptom be related to an underlying illness?
  • Am I drinking too much coffee or alcohol or smoking too much?
  • Do I have a healthy diet?
  • Am I sleeping enough?
  • Have I been exposed to anything unusual in the air or my environment?
  • Asking yourself these questions can help limit the number of possible causes and may lead you to an answer more quickly.
