lol Terry. I called NHS direct on Sat morning. They did recommend a MI unit but the nearest one is 15 miles away and I had no way of getting there. I decided to strap it up and take ibuprofen. It's now only strapped up part time and the swelling has reduced as has the pain, so I think we are getting there.
Btw, it wasn't (unusually for me) a miscellaneous drinking injury - I did it at the park with my stepson. It was only afterwards that I had a couple of glasses of wine (although it probably would have hurt less had i done after said wine!!)
