Hi nannoo,
Welcome to NeuroTalk!
Sorry you are in such pain.
Since you have multiple meds and it's a weekend, can you call your chemist/pharmacist to have the chemist/pharmacist help you to determine which additional meds are safest for you?
Contact your doctor this coming week about the pregabalin dose. It's likely the doctor has started you at this dose for a reason.
Have you found any topicals helpful?
I am sorry I can't be more helpful. I don't want to cause you any potential for a dangerous interaction.
I hope you find relief, soon!
Warmly,
DejaVu
