14 mos since a grade 3 sprain in right ankle and still have bruising and slight swelling around top of my ankle, is something still wrong?

THe good news is . You didn't say you had pain. I would advise you to wear some form of compressive anklet to minimize the swelling. Ice it when you can and elevate your feet when at rest. A grade 3 sprain is on the severe side and discoloration is not usual, nor is slight swelling.
Yes. Continued pain more than a year after a sprain can be a sign of other more serious problems.
