i can understand your condition. i hope you are not in too much pain now.
you can take a tab. aceclofenac 100mg and paracetamol 325mg combination twice a day for pain.
also since your posture is a big problem, i would suggest you to do yoga and certain core strengthening exercises.
also take frequent breaks from front of your computer. like atlas go for a walk or something for two minutes at least.
consult a physiotherapist for further guidance.
take a calcium supplement like tab. sparkle pro once a day after food for 30 days and tab. d3 must 60k once a week for 3 months.
