I eventually got through to a dentist yesterday and he told me I was suffering from a condition where the nerve end on a tooth decides to die often after having dental surgery like the kind I had a while ago to have some inlays put in. Unfortunately not much can really be done for up to 24hrs until the pain in most cases dies away by itself the nerve end eventually dies and stops reporting pain to my head, eyes and general half of my face.

He told me I had to take two lots of pain killers that I could get to kick in at certain times after one had lost its effect. You usually have to wait about 4-6 hours before you can take more of that particular pain killer. At the moment I'm in a waiting period before I can take the next lot and can only numb the pain by rinsing my mouth with vodka or applying bonjela.
