Post injection pain

My Retina Specialist tells me that the EXTREME pain I am experiencing post injection is due to the Betadine application prior to injection. This pain lasts 12 to 18 hours and has become INTOLERABLE. I have stopped these injections after receiving them for 13 months. I need help. I live in the high desert in So. Calif. I am looking for Retina Specialists in So. Calif who use
Chlorhexidone instead of Betadine. I've found a med. group in Sacramento and one in Fresno that use this. That would require 3 to 7 hour road trips. These trips would pose a huge inconvenience to me. I have wet AMD in both eyes. I am 75 years old and take care of my 78 year old wife who is disabled.
Currently all bleeding and leakage has stopped. I am hoping that someone in So. Calif uses this alternative, Chlorhexidone Gluconate. Please let me know if you know who uses this alternative. TK u
