Does this sound familiar? I have clients come to me with this problem and found out that although there's nothing wrong with their discs or nerves but everything going wrong with the muscles around the spine, around the pelvis, hips and thigh. Muscle imbalance can create havoc in the low back with muscles on one side being tighter than the opposite side. This can be due to repetitive muscle use, poor habitual body positioning or poor body mechanics.
Advanced massage techniques, range of motion exercises and active assisted stretching will do the trick. No need for prescriptions, steroids or surgery. You wouldn't use a mallet on a small nail would you?
