knee woes

now that i've started pt back up, i'm starting to get more worried about my knee. the lumps that were bothering me before are even bigger now, and even more bothersome. my knee's definitely catching, right where one of the lumps is. that catching gets in the way of almost every exercise i have to do.

my thigh is still super, super sore, which is weird because i've never had problems in that area. sometimes my thigh just radiates with pain. my therapist won't give me any additional exercises because the ones she wants to add involve squatting, which is too painful for me to do, and i've historically had problems with squatting since my first surgery.

sigh. :(
