<s>[INST] the left side of my neck (right where my shoulder and my neck meet) hurts when i breathe in deeply. Its not a shooting, excrutiating pain, just annoying and weird pain. I was sitting in bed last night when this started, so im pretty sure its not from sleeping on it wrong. Is this something serious? [/INST] U seems to have pulled up uour neck muscle due to bad posture. Apply any pain killer ointment and do hotfomentation for twice daily 2-3 days. If not relieved visit a doctor. </s>
