[|Human|] I have some sort of pea sized lump on my armpit.  Im not sure if it is due to an ingrown hair or if it is something I should be more concerned about.  I have also been experiencing a sore neck (in back) only when I turn my head to the left or right.  I have not been sleeping on a bed for several months--instead sleeping on a sofa.  So, should I be worried?
