pain in collar bone

[tjsway]

the title explains my worry,
anyone else experience this?
also, sometimes when this happened, my jaw locks up when moving, and if i move my head a certain way, my neck muscles feel.... locked..

its strange, and really concerning.
but i feel like it could be attributed to tense muscles and the way i lie on my stomache all day
is this possible?
 
also, side question, can you be tense without consiously knowing about it?
i have so many worries, but i'll try to keep it to one per post.
please help

Yes, you can most definitely be tense without being aware of it!!  I think we all can attest to that.  I occasionally have gotten sharp pains in my collar bone.  Personally, it sounds like anxiety and tension.  If it continues to be a worry...get it checked out.
