I tried to go 8 months with a fractured scaphoid because I didn't have insurance. Definitely could not surf. Hurt like hell doing random things like turning door knobs.
Eventually got surgery and a screw/bone graft to fix the fracture once all the scar tissue and improperly healed bone was removed. Almost a year later still only had like 70% mobility with some pain, even wearing brace while surfing. Im at 3 years after now with no pain and back to 90% mobility and surfing pain free with no brace.
I hate to be the guy to say it, but I think you need surgery. It sounds like you agitated the fracture.
Doc said blood supply to scaphoid is awful which causes long recovery, but hooked me up with a bone growth stimulator. Kinda lame it's designed to stop working after 6 months :/
