bic: yes on the day of lifting decreasing to none the day after.
bic: Slightly knock-kneed if either.
bic: hmmm, I'm female...probably. One of the earlier things I tried that seemed to help some was/is to use a wider stance.
bic: Yes, but pulling knees together while sitting significantly relieves the pain. Walking around is no problem.
bic: Sometimes, with ATG squats there is pain behind my right knee. More stretching of hams w/ unweighted squats to warm up more "fixes" this pain for that session.
bic: Thank you so much, obatiger11, for taking the time to answer so thoroughly. This helps me with the names of things to google and an idea of what to try re: stretching. I'd already planned on giving the knees a break next week so I'll try warming up and stretching as you suggest with no leg work beyond walking.
