Recovery after Bimalleolar Fracture & Torn Ligament

I was NWB for three months due to a ligament tear along with fracturing my fibula and tibia. It has been 9 months since my surgery (Dec 24), and although I've been walking independently for a few months, my ankle still swells after a few hours if it's not elevated. When elevated, it becomes stiff. I've been doing PT since Mar 24 and started massage therapy and acupuncture a month ago. Has anyone else had a similar experience?
