and some swelling in my left knee
(previously twisted it in HS, approx. 8-9 years ago, never went to MD). I initially just assumed it was from running around so much since it usually did that after I would be on my feet for more than 8 hours (used to work retail). However, after 3-4 weeks the pain never went away and only got worse.
