That's very interesting. I could have used some of that yesterday. I had burning as never before. I got the shot in the morning and by the time I took a nap and awoke, I was going out of my mind with pain as if someone poured hydrochloric acid in my eye. The office was by then closed and I almost called 911. The morning of the injection, I asked for extra numbing drops and I think the tech over did it. He put drop after drop, waited and repeated the drops several times. The needle did hurt less but I suspect the tissue was damaged by the all the numbing drops because the treated eye is still extremely fuzzy 24 hours later and usually it is clear after a day. Despite the beginning of wet MD my acuity in the affected eye is pretty good however today I seriously fear permanent damage has been done. Pain has never driven me to tears but yesterday I moaned, howled and thrashed about like a madman. My poor little dog didn't know what to think. Ultimately I found a sample Lidocaine Gel 3.5% that they gave me at our first session. It stung worse than acid but temporarily relieved the pain so that I could skip dinner and go straight to bed. For the entire week prior to yesterday I had been making arrangements (with both parties) to obtain a "second opinion". I had every intention of staying with my present provider if told to do so. I hope this was not intended to be a send-off gift. By the way, I am allergic to oral erythromycin. Is it the same chemically?
