Hi I am Juli, female, 65. I have had daily 24/7 'head pain' over 45+ years. It can only be treated daily, not prevented. I've been to an untold number of inpatient hospitals, neurologists, headache specialists, pain specialists, ad nauseam. I utilized FMLA updated monthly as per employment rules by my neurosurgeon at the time until finally applying for permanent disability approved immediately.
I could never name all on label/off label meds. It's the same predictable head pain daily that builds up and needs to be cut down to level 3-4.
That is my story in nutshell lol!
