Amazing!! I will admit I was skeptical. My skepticism was wrong! Been battling allergy and sinus issues for months. Today was no different. Woke this morning with terrible allergies, sinus pressure, and a headache. About 15, maybe 20, minutes into the session I swear I felt an internal “pop”. Immediately had a small coughing spell from the drainage, but the pressure, headache were gone! Thank you!
