Yesterday, I noticed that at the spinal cord area, I found a lump that slightly showed up a bit. Like in the pic upon

At first, i didn't know what it was, I thought that was just fat 'cause I'm a bit chubby and I don't do workout very often. But then that thought definitely gone away when I saw that the bump like fat-stuff was thicker than the skin around that spot. But I still not sure so I went on to the Alation group to ask for an answer, and I got the answer as what I thought

After dis, I got a theory about the symptoms which would let u know that ur body is developing tail
+ Got the phantom tail feeling
+ U may sometimes find it hard to sit comfortably on any chairs that have the back part
+ Have the soreness, hurt, uncomfortable, twitching feeling or any pain, weird feeling at the spot, where u used to suppose no having any strange feeling before. Sometimes u may get the tired back feeling at the spinal cord like the olders often have
+ U may can control ur tail in somehow ways whenever u want.
