i have several balls around my knee area that really bother me. it hurts to stretch but after i am warmed up i can complete my entire work-out. unfortunately, by the next day i am feeling the pain. i have gone to get a massage where the balls have been broken and the pain goes away. my question is it safe to have the balls broken? is there a general cause to getting these horrible balls?
