I had a trimalleolar fracture of my ankle 5 years ago that healed without surgery. i have always had pain, but recently its gotten much worse. why?

Arthritis: You've probably got some arthritis building up in the joint. X-rays and a consult with an orthopedist would be next steps.

Postrauma arthritis: Tri malleolar frx are best treaedt with surgery early to reduce chance of late arthritis looks like you fall into that category.

Probably: early arthritis forming in the joint. You should see your local Dr for evaluation and possible treatment options.
