@cskippy No. I researched about red-light therapy and the amazing results with it. After a few swallow studies, it showed the flap that keeps food from entering the lungs (epiglottis) was not doing its job. After that, I ramped up the red-light therapy. The last swallow study showed it was working as it should--thank God. I remember the doctor saying it was "astounding" that it was working so well "now." This was the same doctor that evaluated the other studies. Being human, I cannot say with 100% certainty that the red-light was the reason but cannot rule it out either. There are articles about this topic, especially on JAMA. You can purchase a little red-light wand on eBay for around $20.
