Back pain

Hi Pals,

For the past few weeks, I am having back ache when I wake up in the morning. Thankfully, the pain is not considerable for 6-7 hours and I am able to have a peaceful sleep. The problem starts post 7 hours where the lower back ache starts.

I play badminton daily for an hour. I sleep on a normal bed which is neither too hard and nor too soft. Can you please suggest me something useful to get rid of this pain?

I am slightly obese and will this be a reason?

Cheers.
