But then up and pain subsided. Possibly knee cap
moved back in place. Now then in morning knee
lil swollen, pain when walking, no bending or squatting which would lead my proffessional opinion to be you over streched tendons, possibly a slight tear. Use an ice pack for 2 days twice a day 30 mins each. No more weights till Friday. If everything returns to normal leave the squats out for an additional week. However by this Friday if knee is still the same, go see family doctor.
