I do like moist heat but I use an infrared platinum heating pad for my back, elbow and knee as it can bend and has 2 different size Velcro straps for back and limbs or over the shoulder. Infrared platinum heating pad can reach muscles 2-1/2" into the muscle as opposed to a regular heating pad that only goes 1/2" in your muscle. Not sure the statistics for moist heat which is also helpful.
Be careful with moist heat as I had numbness in my back and I ended up burning myself with a hot water bottle and the Massage Therapist noticed I burned myself only like a sunburn so it wasn't as bad. Infrared is not used for anyone with a spinal cord stimulator implant but for hardware from surgery not recommended but you could speak with your Dr. about it first.
I'm not saying that my herniated disc was healed by the infrared platinum heating pad but was not seen on my second MRI 15 months after using the infrared platinum heating pad which my Pain Management Dr. recommended to me for the treatment of pain from an annular tear. Sara
