A couple of years ago I had a stellate ganglion nerve block that I had an unusual reaction to, like a chemical burn over my neck/chest that lasted 4 weeks amongst other stuff. However, Horner's Syndrome I know was expected, but my eye still seems smaller than the other, so much so, a doctor recently asked what was going on with the left eye? I haven't been wanting to be in photos much, but I notice in every single one the left eye looks like upper lid droopy, like it's swollen and this eye is smaller. Could this be due to that Nerve block still? could it have cause permanent damage?
