Elevate, elevate, elevate
It really is the main thing that helps with the swelling. And not just a little bit on a foot stool, you want it above your boobs for at least 2 hrs at a time most of the day, and all night (put it on pillows)
I jumped off a wall and landed on my foot stretched out, heard a snap, went for an Xray....oh just a bad sprain, you will be fine in 8 weeks.
I had 4 dc, youngest was 10 months and we moved house when the ankle was 7 weeks post crunch. I wrapped it and got on with it, told myself the doctor said it would be painful etc.
At 9 weeks the pain was still dreadful, I went back to the doctor, more xrays, different angles....oh you did break it after all, its just an unusual spot, mostly snowboarders break their ankles that way! Oh dear it has healed crooked, we can do anything about it, it shouldnt be too bad when you are older and have arthritis....grrrrrrrrrrrrrr
PLEASE stay off it for a week and if it isnt better go back and make a fuss. Ankles are notorious for hiding the break as they have so many little bones. In fact, if you can afford 150 pounds for a private appointment, go and see a private orthopedist who specialises in ankles. They can assess you and then put you back into the NHS for scans, but you get an expert opinion, not a rushed A and E generalist
