Poor you Helen. I had one years ago that really was bloodshot. Depending on how bad it is, it can take some time to disperse. Mine happened when at work and I was advised to see my practice nurse to get some drops to stop it leaving a stain on the eye white.
Don't want to worry you as it may go back quickly and normally. I don't know what drops you have got, but if something that you have picked up yourself, it might pay you to see a pharmacist and see what he or she recommends.
I am now a widow and live with my memories.
