from waist up, i am thin, however, my thighs and legs are fat. i have a very hectic school schedule. during these times, i often get comments from my friends telling me i am getting thinner. i only lose weight from waist up, too. it's as if i have edema, or something (but of course, i can't really tell...). i don't really want to do exercises since i experience chest pains sometimes. i haven't consulted a doctor, yet. what do i do? perhaps some of you can give me just some idea of what i might be experiencing. thank you.
