I have been diagnosed with opthamalic shingles. Cultures came back positive. I was prescribed acyclovir from PCP and neomycin(maxitrol) drops for my eye from an opthamalogist. The swelling in my eye is insane, to the point it won t open. I called my doctor immediately and she said it was from the shingles not the neomycin. My question is how can I be prescribed something for shingles that warns to not use if you have shingles? Am I wrong in thinking the extreme swelling is from the eyedrops? Thank you
