I need help with ankle injury

I injured my ankle about eight weeks ago and I've had it checked by a therapist who told me it was tendonitis. They strapped it for me and gave me some heat treatment but it didn't seem to help much.

A few weeks after the pain started it got worse so I went to my doctor. It was so bad by then I couldn't even climb the stairs to see them, they had to come down and see me.

They've given me a prescription which works out at about sixteen painkillers a day but I stop taking the codeine because there was a warning on the leaflet saying that they were addictive and they didn't stop the pain anyway so there was no point. They agreed it was tendonitis.

Since then the pains pretty bad still although not as bad because I've been using an anti inflammatory but the swelling is getting worse and is now on the inner and outer side of my ankle and achilles tendon is swelling as well.

I've been told that my doctor shouldn't have just sent me away with painkillers they should have sent me for an x.ray.

Has anyone experienced anything like this or have any tips?
