Q. My son is complaining about back pain. I also see that his back isn't straight. What can we do? My son is a adorable 8 years old. He is complaining about back pain, that bothers him after he walks a little. I also saw that his back isn't straight and looks like a S. is this deformity connected to his back pain?

A. The normal shape of the spine is very similar to the "S" shape as you can see here
But even if his back isn't deformated, he has back pain and you need to take care of that by going to your pediatrician.

Q. I want to know the treatments for back pain

A. well, tester1234, you are asking a very general question. back pain is a symptom. and the best way to get rid of a symptom is by eliminating the cause. back pain have many causes- not sitting right, posture problems, Spinal disc herniation, muscles not strong and long enough, kidney problems sometime feels like lower back problems. i had a problem with posture. so i went to Rolfing therapist- really helped.

Q. I have a lower back pain for more than 3 months what should I do? I am a 55 years old man, and i work as a truck-driver. In the last 3 months i have a back ache that is disturbing my life. Its really annoying me. When I wake up I am usually fine, but after 10 minutes of driving the pain starts and it doesn't stop till I go back to bed. What can I do? my GP told me to take Tylenol, but it's just not helping.

A. A constant low back pain can be a result of a lot of things. A friend of mine (63 years old) had a back pain and she didn't pay enough attention to it assuming its just nothing. In the end it was due to metastatic lung cancer.
