DH thinks it wasn't necessary, I think it was.
DH cut his hand on a glass while washing up, the cut is between two of his fingers and is about 3.5mm deep. He's basically cut straight through the webbing between his fingers. It bled profusely. We packed it well with gauze and wrapped a bandage around it which stopped the bleeding (both first aid trained, as we teach bushcraft/whittling). We rang the GP surgery who told us to go to A&E if we thought it needed stitching.
The nearest minor injuries unit is in a different town 30 miles away and neither of us drives (medical reasons). DH thought it would be fine and we should just leave it, I thought it might need stitching/might still have glass in it and we should go to A&E
So we went to A&E and DH was made even twitchier by the screens and posters blaring out the message that we shouldn't be there unless we had a genuine emergency, could we go to minor injuries instead etc etc. Triage nurse ordered an x-ray to make sure there wasn't any glass in the wound, then about half an hour later he was seen by a nurse who said it couldn't be stitched because of where it was. She glued it, stuck it together with steri-strips (which wasn't very successful because as soon as DH's dressing came off it was bleeding profusely again) and wrapped the bandage back around it.
DH thinks he was right all along and we needn't have bothered going. I think it was better to be on the safe side and it is a very nasty cut in a very nasty place.
So who IBU?
