COVID Institute Launches Nation’s First Epipharyngeal Abrasive Therapy Program for ‘Razor-Blade Throat’

COVID Institute now offering US clinical program for treating the sore-throat phenomenon, “razor-blade throat.”

PLANO, TX, UNITED STATES, June 25, 2025 /EINPresswire.com/ -- COVID Institute today announced the United States’ first clinical program dedicated to treating the severe sore-throat phenomenon popularly dubbed “razor-blade throat.” The clinic now offers Epipharyngeal Abrasive Therapy (EAT), a non-invasive procedure performed in more than 100 Japanese ear-nose-throat centers.

A Growing Problem

Emergency-department physicians report that sore throat appears in roughly two-thirds of patients infected with the NB.1.8.1 (“Nimbus”) variant, with many describing the pain as “swallowing razor blades,” according to ABC News (June 19 2025). An 11,700-person survey in China found 65 percent experienced throat pain and one-third rated it “severe” (JMIR Public Health, April 2025).

Why Conventional Remedies Miss the Mark

Inflammation often hides in the epipharynx, a thumb-sized patch of tissue behind the nasal cavity that routine “say ahh” exams cannot visualize. Persistent swelling irritates local nerves, amplifying pain and triggering autonomic dysfunction.

How EAT Works

EAT gently abrades the inflamed epipharyngeal tissue under endoscopic (thin flexible camera) guidance, promoting healthy healing and modulating vagus-nerve pathways. Each session lasts about ten minutes; most patients resume normal activities the same day.

Key Benefits Reported by Patients

• Directly targets hidden epipharyngeal inflammation
• May reduce throat pain, fatigue, and post-nasal drip
• Supports autonomic balance in dysautonomia and POTS
• Non-surgical; no systemic drug exposure

“Many Long COVID patients describe throat pain as their most debilitating symptom,” said Robert Groysman, MD, medical director of COVID Institute. “EAT allows us to treat the exact spot conventional therapies overlook, often with rapid improvements in comfort and energy.”

Patient Perspective
"The EAT procedures were able to get rid of all the focal inflammation, so my son was able to further progress to get rid of the POTS PEM and chronic fatigue.” - S.S.” (Quote used with permission.)

EAT consultations can be booked at covidinstitute.org/contact-us or by calling (214) 390-7557. Telemedicine evaluations are offered for national and international patients. Limited appointments are available while capacity is expanded.
