I recently recovered from a nasty bout of bronchitis. I haven’t had a chest cold in many years. I did successfully use the m1 to treat my sinuses. Below is a copy of email I sent to Bob:
I have found that your M1 helps with sinus infections. Proof of concept, video of a woman with a different pemf system for sinus condition: Reference: https://youtu.be/cPUO_hlUFh4
My protocol, started on Saturday afternoon, 3/9/19 Omni8, coils taped together for max output. Coils placed directly on top of left or right sinus cavity. There was an immediate positive effect on clearing sinuses, thought it was placebo, but was repeatable. I would occasionally hear crackling on my sinus cavity during treatment as my nasal cavity opened up. This works, I’ll bet other people should experience the same.
Hopefully this info can help someone.
Addendum: I have suffered from allergies in the past, occasional flare ups, my ENT even recommended surgery to trim my sinuses several years ago, didn’t do that! I am experimenting with the m1 for ‘general maintainence’ sinus treatments.
