A 30 years old woman suffered from Hoarseness for a long time. She had a low grade of bacterial infection in her throat, for years; it felt constantly like being close to be sick, as if she is about to cough but actually repeatedly had to clear her throat. Her voice was broken, rusty, as if she drank a lot of alcohol. MT verified that this is indeed strap infection, and within a few weeks of IPEC clearing, the strap was gone and all symptoms cleared, and her voice stopped being hoarse and went back to normal.
