B love, I have awful jaw pain and yes it's from nerve--my tumour is pressing on it and the jawbone has nearly already 'gone', which has left the nerve exposed. As well as my ibuprofen and co-codamol, whilst in CA at Easter, I discovered 'oragel max' which helps to deaden the inside lip-pain 'Little men with knives'--outside is completely numb! Biopsy has actuall y 'eased' some of the jaw pain higher up once i recovered from the procedure.
As well as hugely swollen face, I also now have 'bags of water'below and above eye---icing the area helps a bit
