Pain...

I want to go to an orthopedic hospital because I feel pain at my waist. To tell the truth, I have the pain from 2 years ago. Maybe, I can think 2 causes about it. First, I play the contrabass. The contrabass is very big. I feel the strong load to my waist when I play it. Second, I have part time job. I must stand during about 5 hours. I think it is bad for my waist too.
I will go to an orthopedic hospital when I have enough time.
