Fow Long Does Pain Persist After A Fracture Heal?

I fractured my scaphoid bone (it was a crack not a break) and I had the plaster removed a week ago. I am in agony with the pain of it. I was asked if I wanted physio and I said no. So how long before the pain goes away (pain killers - co-codamol 500/30 and Gabapentin dont touch it)
