I sprained my ankle over 3 months ago in rugby i'm playing again it is still swollen bruised i can run but it i turn it wrong it hurt is it ok to play?

Ankle sprain: If the initial injury was over 3 months ago and your ankle is still swollen and bruised, it might be more than sprained. It would be helpful to see an orthopedist, and get an xray. You might also need to have MRI if the orthopedist suspects a ligament injury. Until then, it is probably making things worse to continue to play on it.

See a podiatrist: With continued pain over a long period of time since the initial injury you should seek medical attention. There could be many underlying issues related directly to the injury or compensatory in nature as well at this time.

Not ok: You should have it checked out, possibly xrays are necessary - there could be a small fracture present as well as the sprain. The ankle needs to be properly rehabilitated, and braced / strapped for some time after the injury.

Ankle injury: I would suggest you see a doc. It's not right for it to hurt that long. Also, you need to wear protective wear while playing to avoid re-injury.
