The variety of solutions people have mentioned in this topic is a testament to the complex and varying nature of back pain (and the body in general, if you'd like to go there). I would therefore like to add my personal savior: Hamstring stretches. Changing your lifestyle (not necessarily drastically) and excercising/stretching in general is the solution in most cases, yes, but for me the single greatest contributor was the hamstring stretch. Lie flat on your back, keep your legs straight and raise one until you feel its back sides burn. Strain it a little; using a towel, rope, bedsheet or spare pair of pants to pull on your heel if necessary. IANAD, but I hear it's pretty hard to injure your spine this way.
