Can scratching in the eye 6 days after an upper eyelid surgery caus issues?

Had upper eyelid surgery 6 days ago, The eyes have been very sensitive to light, last night though while sleeping I woke up with me eyes like something was in it scratching it, and is now continuing throughout the day, it's bloodshot and non stop watering and I can not open it due to the scratching irritation,I'm taking fake eye tear drops and also drops for infection, I'm having stitches out tomorrow but from a different doctors because I went overseas for my op as I live on a very small island
