Brief Answer:
Further Clinical evaluation necessary...

Detailed Answer:
Hello,

Well, the pain and apparent freezing feeling could be due to some nerve compression at the mid-lower neck regional (intervertebral disk space) which usually runs downwards to the extremities...

Since there's numbness, you should get yourself checked up by an Orthopedics, a thorough clinical examination along with some relevant investigations (Lumbo-Sacral spinal X-ray, Metabolic profile assessment) may also be needed thereafter...Treatment will be depending on the findings...

Meanwhile, for symptomatic relief, take complete rest...avoid twisting/bending the neck, sit in an upright posture and, refrain from any unsupervised exercises for the time being as well...

You may take tab Hifenac-P after some food for the next 2-3days...

Take Care
Kind Regards
