Symptoms like the ones that you describe can be very normal during the PRK healing phase.  Healing from PRK presents much more variability from patient to patient and eye to eye than LASIK.  I think it wouldn't be a bad idea for you to see your doctor; it will...

Because PRK necessitates the regrowth of tissue on the top of the cornea, it can be frustrating for patients. Nothing that I am reading about your description would make me nervous as a surgeon who performs PRK on a weekly basis. Keep using your tears, and keep your appointments with your doctor.
