I posted something about this awhile back in the Workout forum thinking that my issue may be related to working out, but here is what I am noticing.
I would say the past few months, when I squat down, without any weight, I have trouble getting back up. It seems that in that position that I do not have the strength to get back up sometimes. It is just at the beginning when I am trying to stand up. It is weird. It don't really hurt in my knees or anything.
I started thinking that maybe I was working my legs too hard, so I gave legs a break for about 3 weeks now. Nothing really changed and I am starting to doubt that was the cause. Then I started thinking....I started doing quad shots about 3 months ago roughly. That is all I do now. My current cycle I am shooting a little over 3 cc's per quad per week. They are painless, but I noticed that the last shot I did felt a little odd in my knee. Not pain or anything, but the same type of feeling that I get when I try to stand up.
Could quad shoots cause something like this?
Sorry for the long post.
