Sometimes the weather can trigger a migraine. Keep a migraine/headache diary. Take it with you to your doctors appointment.
At the drs office, talk about your migraine/headache in graphic detail just like you did here. Don't leave nothing out.
If you have to, take notes with you.
Ask the doctor a lot of questions. Make the doctor talk to you in
laymens terms.
Whatever meds the doctor prescribes pump the doc with questions on
ALL THE SIDE EFFECTS. Do not under any circumstances take the docs word for it either.
Always follow-up by doing your own research.
Go to the library and/or research online.
Good luck!
