Hi
The headaches come and go in waves.
As soon as he feels the onset, he takes the nasal spray and other meds and it is more manageable and less frightening . He is not in control of when they happen, but is able to control and manage the pain better.
My advise is to always have a supply of meds so the second your son feels a headache coming, he can take the meds.
We learnt a lesson, when we weren’t prepared, had to phone doc to get telephone consultation, then go to chemist for prescription by which time, the headache had kicked in. So we always have a few days meds so are prepared for when they start again.
I am not sure if alcohol intake has something to do with the waves of headaches. When my son was initially diagnosed, it coincided with him partying hard at the weekends, out with the lads, having a good drink. However, I would go to say, that he has settled down, and not drinking so much/partying and the waves of headaches have also settled down.
As a parent watching your child, regardless of their age, suffering the intense pain, that these headaches cause, is horrible and frightening,
but it does get easier.
