Sorry I didn't realize your original post said your age.
How old are you? and because of doctor patient confidentiality your parents wouldnt have to know anything. Just make an appt go in and let the dr. know what is going on. Trust me, legally there is no way for him to get your parents involved
you sure there isnt any other way i can fix this?
damn i didnt want to get my parents into this...
The best thing for you to do is be seen by a physician. This doesnt sound like something you can just fix on your own.
