This is a short note to thank you again for your delivery and explanation of the ELFcare unit to my husband  2 months ago. Since then he has used it daily, sometimes several times daily, when his shoulder and arm pain is at its worst. Being a quadriplegic from a landmine in Vietnam, he has put his arms and shoulders to much use over the last 45 years to remain as active and healthy as possible. The pain was severely restricting his mobility. Prescribed anti-inflammatories present their own problems with side effects for him.  I applaud our Doctor and Therapist for offering this to us. The Elfcare greatly diminishes the pain, decreasing the need for medication except at the most severe pain. It allows a comfortable night’s sleep, instead of waking with pain. This has been a huge help and a big relief for him. Any form of pain relief with as little medication as possible is great in our book!!
