I'm a 15 female , and I'm slightly worried about this pain I've been having under neathe my ribs on the left side . It's a sharp pain that lasts at least up to 5 seconds . When I sit a certain way, the pain comes, when I laydown and take deep breaths it hurts , also , I get the same sharp pain between the back of my knee and butt . It comes almost random but hurts for a few seconds . I seen a doctor awhile ago about the same thing , and he said I was fine . But now there hurting alot more then they did before . I'm kinda worried about what it might be and if it will effect me playing sports. Anyways , I just want to know if anyone has expirence this , and if they had , what did you do to help ease the pain , or completely fix it .

Tasha .
