Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain long hours of driving or sitting is a common cause for causing back pain..
It can lead to hunching of the back and continuous strain can lead to pain..
I would suggest you to consult an Orthopedician and get evaluated and a thorough clinical evaluation is commonly helpful in diagnosis and if needed you can be advised to get an x ray or MRI Scan done to rule out the exact cause as there can be other common cause of back ache like Traumatic injury,
Arthritis,
muscle strain etc..
You can be advised to take anti inflammatory painkiller like Ibuprofen,
muscle relaxant like Chlorzoxasone, doing warm compresses, stretching exercises and
Physiotherapy can help..
Apply
analgesic gel and massage with analgesic oils can relieve..
You can also tie back support brace or belt while driving or sitting.
Look for alternative methods so that you have to drive less..
Hope this information helps..
Thanks and regards.
