Hi there ~
I understand your concerns. Pain after landing onto either of the chin over a year ago with continued concerns would mean that you might need to have your chin imaged. That would mean you should have an x ray
or a CT scan
of the region done. I believe that you will do well with all the problems if you start taking medications after visiting with a doctor who is specialized in orthopedic issues.
I hope this helps. Take care! Have a lovely day!
