last week when i was doing squats i notice a slight pain in the knee joint of my right leg. i can sometimes feel it now when i stand up or walk up stairs. its nothing too big, but im kinda worried about a potential problem arising if im putting heavy weight on it (its not a substantial amount of weight, only about 180). my legs day this week is coming up on wednesday. should i try to work around it, work with lower weight and higher reps til it subsides, or just bag the squats til it goes away? id really hate to stop my progression, but i also dont want to have a torn ligament or something and not be able to do legwork again for a while. what do you guys suggest?
