My son has been complaining sporadically about pain in his leg (no injuries), and sometimes his neck; mainly his left leg more than the neck. I thought it was just him saying things . This began about a month ago. About 2 weeks ago, I noticed a lump/bump in his back, on his spine. It has no discoloration, and doesn t seem to hurt him. I noticed it while caressing his back, I thought it d go away, but it hasn t, seems a tiny bit bigger today. I m a mom, so I m pretty worried and wondering if I should get him seen by his Pediatrician, or if it s not anything at all to worry, maybe neither is connected to the other. Can anyone give me sound advice? Thanks in advance !
