My ankle hurts occasionally, but it's been 2 months since I rolled it. Any way to make it go back to completely normal?

Yes. Use an ankle brace and do range of motion and strengthening exercises.
Eval and Possible PT. After any ankle sprain a good rehab program is key to the fastest recovery and best outcome. You do want to have an evaluation to ensure that there is no other source for the pain. If after physical therapy there is still pain, your doctor will likely order advanced studies to determine if there is need for surgery.
