My husband has a spinal stimulator for low back pain due to spinal stenosis. Can the red light therapy be used in conjunction and how does it affect spinal stenosis if at all?

Because your husband has an implanted spinal cord stimulator, he should consult his pain specialist and the stimulator manufacturer before using red light therapy, particularly over the implant or leads. Red light therapy cannot correct the spinal narrowing caused by spinal stenosis, although it may temporarily ease discomfort in some people. Evidence for low-back pain is mixed, so it should not replace his prescribed treatment.
