These days, I have always been feeling a big sore in my waist and back. Especially these two days, It gets worse and worse. 

I don't know why. Is it because of my wrong position during sleeping? Coz I often get curled up which I heard is bad for the spinal. 

Or is it because I sit all day long? 

Or is it because something goes wrong with body? 

I wish it was the first two reasons. 

I'd rather choose to believe it's because of my sendantary lifestyle without enough exercises leading to my ailments. My mom asked me to go to the hospital to do the check, but I want to watch my body for a while. If it still aches, I will go then.
