Hi,
My daughter had bilateral
vocal cord
nodules for 3 yrs and needed voice
therapy. Turned out, in her case, they were aggravated by severe reflux we never knew she had because it never came up high enough into her mouth for her to feel it, yet it came up to the vocal cords and caused massive pain and cont'd nodules.
After 3 mos on Prevacid and a rescope, they went away completely and have never come back!
Good luck and Welcome!
