Hello Doctor, I am male, age-26, height-5'7", wt-55. I am a software Engineer working for MNC. My job needs me to work in front of computer 8-9 hrs. everyday. My problem is I have a some neck, back, thigh and recently little knee pain also. What should be the reason? Also, I have prolonged indigestion issue too and get gases in stomach. How to prevent all these?
