@Thumbelina: Hi everyone. I'm addicted to cracking! I have to crack my fingers, wrists, toes, back, neck and hips. I'm "double jointed" in my thumbs and they ache if I don't crack them. Recently my right thumb has been really sore at the knuckle ( I think it would be the second) and I can only crack it 2 times instead of the usual 3. I also can't bend it as much. Any idea what this could be? :?: Describe your neck clicking.
