I inquired about DPL in regards to left shoulder pain. I had torn a muscle in the winter and noticed the pain started to worsen this past spring. I started DPL therapy in July. After the first visit, I noticed less pain while driving and an overall decrease in pain. After the fourth visit I noticed a significant decrease in tightness and discomfort. I was able to sleep through the night without pain and noticed an increase in range of motion. I did not realize the amount of pain I was actually in until it began to go away. I would definitely recommend this to anyone with muscular pain. I typically choose to go without taking pain medication and massage therapy can be quite pricey and results can be minimal. DPL has provided the relief without medication or invasive procedures. I am very happy with my results and will continue to use this method for any future injuries.
