Vocal nodules. Mare. kindly advise me.

I have been diagnosed chronic laryngitis n advised to take voice rest and Nervijen-D for 3 months. As my profession is teaching, I can't afford to take complete voice rest but abided to take breaks in between sessions. After 3 months, doc found nodules in V.C (more prominent on the left V.C) and prescribed me antibiotics, anti histamines, anti inflammatory drugs for 5 days with complete voice rest for 10 days. As per symptomatic response, whether to go surgical excision or not can be decided and also cautioned me even with invasive method recurrence likely to happen so in worst case scenario advised me to change my profession. All I want to know is second opinion from this forum, as stated above my voice is asset to me and changing the profession is night mare. Kindly advise me.
