My ankle has been hurting and swollen for six months and I have no idea why

[Demi]

Can anyone offer any explanation?

I've been to see the practice nurse at my surgery and she said I must have injured it and I should give it time. I know I did not injure my ankle, I just woke up one day and it hurt, and six months later it still hurts.

It isn't bad enough to make me limp, but its becoming really annoying. I've taken anti-inflammatories - they do help a bit - but I assume it would not be ideal to take them long term.

Can anyone offer an explanation or advice?

Many thanks.
