Well, l actually feel a bit better this morning, praise be! There seems to have been an endless dribbling and now, although there is still some swelling, it is much less so than previously. Both maxfac and the dentist said the lump l was left with in my cheek was scarring which would remain there and both refused to open the other tooth or incise the swelling on the upper gum despite my ongoing belief that it was the upper 5th which was the source of the problem. I guess we've all learned lessons in this - mine is to be more assertive and not be brow beaten by professionals, one of whom referred to my tooth as 'grumpy'! At least my knee has benefitted from all this extra analgesia. Every cloud and all that!
