I am a 20 year old student who really likes weightlifting. My biggest obstacle is my left knee, which was quite heavily injured 5 years ago while I was playing basketball. It was treated by a surgery followed by physical therapy. However, my left leg has been noticably weaker than my right leg ever since. One of the reasons I started weightlifting was so I could try to fix these imbalances. Foam rolling and wearing a knee sleeve helps me a lot when lifting heavy weights, as it makes me feel almost no pain even when doing, for example, squats or similar exercises. In the last week or so, I noticed that my left knee got a bit swollen. It feels tender to touch, as if it's filled with a liquid. (This is not the first time that this has happened) I feel no pain in the knee however, and I have full range of motion. I've been icing the knee 2 times a day for 20 minutes the last couple of days, but the swelling doesn't seem to be going away. (Given that I've continued strength training as usual)
My question is: Is it okay if I ignore the swelling and just keep exercising normally?
Thank you in advance!
