Q. Im only 17 I have horrble lower back pains. Im constitly rubbing,stretching, or cracking my back. the pain is either a throbbing pain or an ache or sting.I feel it worse when I put my chest out my shoulders back. my back feels like its out of place.

A. Lower back pain is so very common... I have had it for years, and just recently what I found to be very helpful is walking. Even a 30-45 minute walk and then some streching is good. I have hardly had any pain since I started exercising and it feels really good. Swimming is also known to help.
