Sub:- Appointment request with doctor
Dear [Name of the applicant]
With due respect, I am writing this letter to request you for an appointment with me on [date of the appointment] at [time of the appointment] as I am suffering from a very severe case of migraine.
I have had migraines for as long as I can remember but this time, it has gone much worse. The migraines are accompanied with nausea and vomiting. I have vomited quite a few times and it has made me very weak. This time the migraine lasted for 3 days and the pain is unbearable. It is interfering with my daily activities and has put my day-to-day life in a halt. You have treated me earlier too and have given me Advil and Motrin as medications and they have helped me for a while but it doesn’t seem to work now. I am afraid that it might grow worse with time and it would mean a lot if you look into this matter urgently.
It would be a great help, if you help me out here and make out some time in your busy schedule to accept my request for an appointment with you as my condition is getting worse and it’s keeping me from carrying on my daily routine. I hope you will get back to me as soon as possible. I look forward to hearing from you.
