I recetly notice when i was rubbing my back, i felt a bump below my shoulder blades. It feels somewhat moveable, and not hard, but firm.

Later, I was feeling the other side of my back, and I have the same thing on that side. Symatrical to the other side. A bump a little below my shoulder blades, somewhat movable, and firm. They both started hurting after I began messing with them.. but not too much pain.

These 2 "bumps" only appear if i am bending down. And are barely noticable.

If i m standing straight, there are no signs of these 2 bumps.

Is this my anatamoy? Could these be just a muscle, or tendons that i am feeling? Or should i go get them looked at?
