Hi Norm,
It really is hard to say, as every case is different. My curve is similar to yours but much worse, plus I other confounding factors---prior fusion and hardware above that area. I will be having surgery in a few weeks.
Only a neurosurgeon or orthopedic specialists can let you know if you are a heading toward surgery. Your pain level and the potential for curve progression will be key factors.
I will attach my xray. It might make you feel a little better. 😊
