At 8 this morning I fell over and couldn't stand up..luckily I wasn't alone and two friends lifted me and got me into their car...its been over 12 hours and its still swollen around my outer ankle and I can't walk on it without help or using some crutches I had in the house. I don't want to go to hospital for a sprain but I'm worried as I've not had one before and can't tell if it really needs looking at...I can move it but not very well and can't put weight on it..I can wiggle my toes so assuming it is actually a sprain but looking for opinion on whether I should see how I go overnight or whether I need to go in?
