Mind and body and biochemistry are a continuum. Sounds like you tweaked something in your back when your reached too far. Liver-Flush an Coffee-Enema help to relieve and release the pain. Magnesium relaxes muscles and flushing the liver gets rid of metabolic waste, which pain and all disease processes produce. This is why in old days castor oil was good for EVERYTHING.
Another thing to consider is the position during the CE. Were you laying down in the bathtub with you knees up? This position shortens the Psoas (the muscle likely causing your pain) and gives it a chance to relax.
In order to fully resolve your pain i recommend seeing a really good Neuromuscular therapist (therapeutic form of massage) for a few sessions. They will analyse your posture and breing you back to health through correct application of pressure.
