I went to Specsavers last week and my daughter has swelling in her optic nerve. I was told if she has any headaches, sickness or vision problems to take her to a&e straight away. She seems fine in herself besides a bad headache the week before going to Specsavers and has an urgent appointment to the eye hospital this week. Has anyone been through anything similar? She also have a problem with a valve in her heart so we've done a fair amount of hospital trips in the past. Thank you
