Several months ago i used to massage my hyoid from side to side (and i confess i sometimes exaggerated) from that time to now whenever i turn my neck i feel the hyoid crack, and also a "pop" sound similar to a drop falling, which can be?

The sound is more likely from the muscles than the hyoid bone per se. What you described is not a cause for concern. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health!
