<s>[INST] I am feeling a sudden back pain which is just 2inches below the neck, it comes suddenly, feeling like more burning rather than pain, after rubbing that part it disappears. I'm getting it sometimes but today it happened thrice. What it is? [/INST] Hi,Sonads. Thanks for query, It seems that you might have some muscle catch giving stiffness of muscles. Take analgesic tab. Apply analgesic cream. Ok and bye. </s>
