Hello Practo User,
Calcium tablet is not the solution for neck pain.
I'm surprised that educated person like you has taken medications from local pharmacist for such a long time.
Your neck pain may be posture related as you are a banker.
Next Steps
If you wish you can consult online with me.
Health Tips
Please don't self medicate as it can be harmful and any problem diagnosed in early stages is easier to treat.
