I lost some peripheral vision in my left eye a week ago and visited my optician ...he took a photo of my eye and said there was swelling around veins and sent an urgent referral to a specialist . i am waiting for this . MeANWHILE i AM worried .. I have an almost constant dull ache just around my left temple which gets worse then goes again , I keep having waves of almost blackness and a type of dizziness and my eye and brain feel as thought they are under pressure . I also have a kind of sickness at the back of my throat . I want to be sensible and wait for my appt but also don t want to leave something that may be a danger to me ...
