How do I stop cracking my neck and knuckles?

ive been cracking my knuckles for about 2 years now and my neck for about a year. I know that the cracking of bones does NOT cause arthritis but it DOES increase your chances of getitng it. i play guitar and i reli dont want to get arthritis when i grow up but i just cant stop doin it!!

Also i get sore necks every now and then but now i get them very often and damn they hurt!!

i dont wanna end up on a wheelchair either!!

plz help!!! Is there some kind of home-made treatment or do i need to see a doctor?
