After my first shot, I had very bad burning in that eye for 8 to 10 hours. I told the doc on my second shot and, after the shot, he put in a dab of Erythromycin Ophth. Ointment 3.5 GM...and WALLAH! just like magic...no burning. Thank God. I had my 3rd shot yesterday and same thing. In fact he gave me an Rx for the ointment so I could have it at home. So even before your first shot ask the Doc if he/she will use a dab of ointment after the shot to avoid the burning (which was like rubbing a Jalapeno pepper in your eye).
