Hi I sprained my ankle a couple of weeks ago and still not better. Any advice?

Hi I sprained my ankle a couple of weeks ago (like end of september) and i didnt think it was that serious since i just strained the ligaments and it was just swollen tissues and nothing was torn or broken. I dont think i took the RICE treatment too seriously... i rested my foot but didnt ice it as much as I should have. And now after weeks I can walk but there is still some pain and little bit of swelling in the mornings and evenings.I have been going for physio therapy sessions but seems like it gets better and then back to square one.pain comes again. I can walk though but sometimes theres still pain. Is that normal? Do you think it will still get better or have i damaged it forever?
