A Week And A Half Ago I Had A Trabectome

A week and a half ago I had a trabectome and cataract surgery. Until today I've felt okay, but last night all night I experience headache and slight nausea. The eyedrops I am taking are : Prednisone (each hour) Prolensa (once a day) and Pilocarpine 4 times a day. I have dizziness as well. Before I was allergic to Timolol which made me dizzy and headachy and had to stop taking for glaucoma. Headache is still present as is slight nausea and dizziness. Any ideas
