I broke my ribs during the last week of February, 2012. My doctor said that there was nothing that they could give me to help me heal my ribs, other than rest and that, on average, it would take about 4 to 6 weeks of excruciating pain for them to heal. I used the Delta Laser and the pictures speak for themselves. After just one week of three treatment sessions a day my ribs started to feel much better and the bruising decreased significantly. And just after two weeks all appearance of a bruise left completely. I highly recommend using this therapy.
