A friend suggested I consider it, to make sure my vision is protected. But I’d never even consider it for eye pain, unless I had an acute injury. Basically had eye pain starting yesterday, and swelling of eyelid. It’s really red and it is quite swollen. Eye is sore every time I blink. But I’m not systemically unwell- normal appetite etc. a quick Google also mentioned get immediate medical attention for pain. But surely conjunctivitis, styes (don’t think it’s that as whole eyelid swollen- no lump or pimple) , all hurt? so why go to A&E? Or am I missing something!
