Itching behind my eye (feels similar like itching of virus herpes on lips during first days before it develops and grows). Blured vision for few seconds, cuple of times a day (like white fog, but not foggy, just everything more flashy, more with light, -more white - like paradise in movies). Does that has anything to do with gangrene or something going on on my tooth root (which dentist says is ok now, but every now end then i feel heavy feeling on gum above tooth and on tooth at night, but during day tooth doesnt hurt, that has been taked care of - canals were cleaned - there was a granulom or something similar). Family doctor sad that heavy feeling and somtimes pain on this half of head is neuralgic nerv - and nobody knows why that happens. He gave me Nalgesin for that. Sometimes hurts just eye, sometimes eyebrow and bone below eye, sometimes ear and gum on this part of head. Really strange. Is something happening to my eye, and that affects from time to time this part of head? I thought it was from tooth (ear, eye, cheeck bone, gum - I thougt it s connected, but dentist sais, that my mouth, gums and everything is ok from dentist view). What s that itching behind my eye? And white flashes? Thanks.
