With 20/20 hindsight I'm pretty sure mine started when I was pregnant with DD in 2016. pregnancy is a common trigger apparently.
Looking back I've had various attacks of pain and vomiting over the last few years that fit the pattern but that I'd assumed were an anxiety symptom.
I think I probably 'lived with it' for about five years.
This year the attacks have got more frequent and more severe, In August this year I had a particularly awful one, and another at the start of September, which resulted in a trip to A&E, a scan, and a diagnosis.
The original plan was 'wait and see' but it just didn't stop, no matter what I did or didn't eat, it was every night. I am taking tramadol and paracetamol daily, and limiting my food intake to periods when I am dosed up, because it I take them to cover all normal meals there are unwanted side effects. I cried on the phone to the GP when ordering my second prescription of tramadol so she re-referred me to surgical.
My case was assessed (13 week wait for that) as urgent and I got a telephone appointment with the surgeon in early December. By that point I was signed off work as I can't function as the tramadol affects my sleep and I was awful at my job (teacher), he said he'd add me to the list for the New Year.
My operation is on the 17th of January: the case notes put a heavy weight on the fact I'm signed off work.
My advice would be don't be afraid to make a fuss, and don't try to 'solider on' in pain. By all means reduce the amount of fat in your diet and stay healthy, but get the painkillers you need, get a fit note if you need to, and push for re-referral if you need it.
