With cumulative effects as cells regain normal function, while also increasing levels of pain-relieving neurotransmitters such as serotonin and β-endorphins in trigger points—hyper-sensitive spots in muscles that can cause pain in distant areas—endorsing laser therapy as an evidence-supported treatment for pain relief, as affirmed by the International Association for the Study of Pain's 2017 Myofascial Pain fact sheet.

as evidenced by both animal and human studies showing reductions in inflammatory markers such as PGE₂ and substance P, which contribute to heightened sensitivity in peripheral nerves. Moreover, LLLT facilitates the healing process by augmenting the presence of neutrophils and macrophages, crucial agents for tissue repair, thereby playing a pivotal role in ensuring sustained pain relief.

which can cause pain and hinder movement. Blockages within this system, whether due to muscle contractions or damage to delicate lymphatic vessels, can contribute to widespread bodily discomfort. Studies underscore the efficacy of the 905nm laser in alleviating arm lymphedema in breast cancer patients, demonstrating sustained reduction in swelling for weeks following treatment.
