I went to the doctors this afternoon because I'd had a dreadful pain in and around the left side of my face fo a few days. It came and went but was possibly the most painful thing I'd eve experienced, with the exception of giving birth to an 8lb 6 baby with no time for drugs 
Dr diagnosed something called trigeminal neuralgia and prescribed Tegretol which seems to have a long list of lovely side effects. Does anyone have any experience of this? Might it just be a one-off or is that it now for ever and ever?
