Masking or blocking pain is quite different from assisting with the underlying cause of pain. Micro-Current Therapy (MCT) by Painmaster is a process of supplying extremely low electrical current, similar to that found naturally in the body, to the affected pain area, where it can reach injured cells, potentially restoring and regenerating them to alleviate chronic pain. More Information HERE Opiods, many pain medications and high level electrical stimulation devices are not designed to help the body’s natural healing process but to mask symptoms. For acute pain this is often the required result, however for ongoing pain the side effects and practical application of these medications and treatments may be negative.
