A 62-year-old lady presents to the medical take with a history of frequent headaches over the past couple of months

A 62-year-old lady presents to the medical take with a history of frequent headaches over the past couple of months, almost every other day, despite the use of ibuprofen, co-codamol and sumatriptan. She reports being unable to focus on her daily tasks due to her constant headache. She has spoken to her GP about it but feels she has not been taken seriously.

She had a car accident 3 months ago that resulted in a broken arm requiring surgery, for which she is still taking regular paracetamol and low-dose tramadol. She has a previous history of mastectomy for breast cancer and her most recent CT CAP showed no recurrence. On assessment, there is no focal neurology present.

Which one of the following is the most likely aetiology of her headache?
