I'm researching information about headaches with these characteristics: [LOCATION]: (Where the pain occurs) [SENSATION]: (How it feels - throbbing, stabbing, dull, etc.) [DURATION]: (How long episodes typically last) [FREQUENCY]: (How often they occur) [TRIGGERS]: (What seems to bring them on, if known) [ASSOCIATED SYMPTOMS]: (Other symptoms that occur with the headache) [RELIEF FACTORS]: (What helps, if anything) Please help me organize research about these headache experiences by: 1. Creating a structured comparison of different headache types that might match these characteristics 2. For each potential type, providing: - Typical patterns and distinguishing features - Common triggers and factors that influence them - Key information points to understand about this type 3. Organizing a list of specific questions that would be helpful to track to better understand these headaches 4. Suggesting reliable information sources for further research Please emphasize that this is for informational research only and not medical advice or diagnosis. Remind me that headaches can have many causes and proper medical evaluation is important.
