i understand where you're coming frm - i'm having ongoing root canal work and it's become infected (again - only the third time in 12 moths - not that i'm counting!) - i found when i was taking the nurofen the pain went away, but i started having lovely little hypo's - decided to give the nurofen the flick, use panadol and put up with a litle bit of the pain - is so much better than the head spins with the hypo's!!! DH agrees - he had the job of picking me up off the floor a couple of times his stress levels are so much lower now..
