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.
