This hits really close to home for me.
I had severe migraines that would last for days over a 6-month period. I’d suffered periodic migraines from the age of 15 but this was something new where even when I didn’t have a “proper” migraine I still had a constant dull headache.
Nearly lost my job even after seeing the company doctor who noted that allowances needed to be made for my sick leave. Saw a neurologist, got an MRI, kept going to the doctor, and no diagnosis came out of it. I eventually had a seizure for the first time in my life and was rushed to hospital.
Finally, got a diagnosis of chronic daily migraines and was put on medication that has controlled them, but the damage it did to my career set me back by years. I was a high performer prior and then I was suddenly blacklisted from promotions because of my sick leave.
My heart really goes out to people struggling with the same pain who have yet to find something that works.
