As with any pain relief treatment, results will vary depending on the patient, the doctor, and the protocol used. When using the MerryBack for the 1st time, you should only feel a gentle relief of pressure on your lower back. You will not feel dramatic pain relief after the first few hours. After wearing the MerryBack, for a couple of hours a day for several days, however, pain relief should be apparent. Don't be discouraged. Also, for maximum decompression, and after it is properly fitted, don't forget to push the upper band downward just before sitting.
