Hello, I'm having a sort of crackling sound on the upper left side of my head whenever I turn my head to the left. Sometimes it happens on the right as well. It sounds like crunching gravel and it feels right inside my head, near the skull. No headache, no ear pain, absolutely nothing except for this sound.
What could it possibly be? Is it serious? I'm hypochondriac, so it's scaring me quite a bit.
