Welcome to the forum.
According to the discription the back pain could be part of a mechanical back pain
complex of symptoms. This mechanical back pain is caused due to bad posture at work, long work-hours in particular position, lack of proper sleep or healthy diet as well.
I suggest you to try back strengthening exercises by extension of the back muscles which can be taught by your Orthopedician or Physiotherapist. This will help to relieve the possible muscle spasm which causes the pain.MRI
can be taken in case you have any nerve
compression symptoms or as deemed necessary by your Orthopedician.
I hope this information has been both informative and helpful for you
