Thanks Thomas for the heads-up. I strongly suspect medial malleolus fracture and possible lateral malleolus fracture. I decided this after I allowed a friend to prod around in my ankle. Very specific spots on my ankle are extremely sensitive and painful - they are less than a fingerprint in size. The medial side is extremely painful when pressure is applied to a specific spot forcing me to flinch.

However, the Wikipedia reference-linkMRI does not indicate - I hope the surgeon finds something, because this pain is getting worse.

Here is the radiology report transcribed verbatim:

Clinical Details: Ongoing pain 3 months post-surgery. ? cause

Technique: Sagittal T1 sequence with STIR sequence, axial proton density and STIR sequence.

Oblique coronal proton density sequence.

Findings:
Metallic artefact is noted associated with the medial malleolus as well as the lateral malleolus.

The adjacent deltoid ligament appears slightly thickened and increased in signal. It appears to be intact.

Hyaline cartilage of the talar dome appears normal.

The anterior talofibular ligament is thickened and ill-defined. The calcaneofibular ligament is also thickened. The posterior talofibular ligament appears intact. The syndesmosis appears intact.

The tendons of the ankle appear intact including the peroneal tendons and both the medial anterior tendons. No significant joint effusion is seen. The subtalar joint appears normal. The sinus tarsi appears normal.

There is a separate bone fragment associated with the tip of the lateral malleolus visible on the sagittal PD sequence.

Impression:
Post-surgical ankle. There is thickening and increased signal involving what appears to be intact deltoid ligament. No other significant abnormality demonstrated.
Please, any clues? I'm sure it's getting worse the more I weight-bear (I've cancelled Physiotherapy for now).
