This is my first post .
OK so last night I was comfortable in bed,
Lay on my back, I stretched out tense and back in a bit of an arch when there was a big crack... The pain seems to be in my spine in between my shoulder blades!
Breathing in I have slight pain but to try move about is unbelievable agony....
So my question is would it be possible I've done any real damage, I've no health insurance so figured I'll ask here before going to hospital, thank you in advance for any help that may be offered.
