Should I go to a doctor?

I practice Brazilian Jiu Jitsu and one day in cl my partner went for a double leg and I fell kinda awkward on my right knee. I fell right on the right side of my knee and as soon as I fell a few seconds later I felt a sharp pain on the knee. Its been a couple of months since it happened, it still hurts whenever I crawl or put my knee on the ground its bearable but it sucks seeing how BJJ is a grappling sport and whenever cl is over my knee is swollen. I've been wearing a knee sleeve and ice it occasionally and that's about it. Also when I put my hand on my knee and bend it, its feels like its crunching and like its rubbing up against something. I stopped training for about a week to see if it healed up, but then it started hurting and swelling up as soon as I started training the next week. Should I waste money going to a doctor so he can tell me "just ice it and take some anti inflammatory" or could it be something serious?
