Hi, Hi. Noted your history about loss of voice, no fever but sleeping too much, wants voice back for singing tomorrow, gargling with cider vinegar, olive oil, drinking lots of throat coat tea with honey and lemon. The basic treatment of loss of voice is voice rest hence I would not advise anyone with similar symptoms to speak, no singing at all unless a proper diagnosis is made. Diagnosis is best made by Endoscopy for larynx as it gives correct diagnosis about the cause. Once this is known further investigations like CT scan or so can be done if cancer is suspected. If laryngitis or such medical reasons then a proper treatment for three weeks with anti-inflammatory and oral steroids if you do not have diabetes can give you cure. If singer s nodules are present then voice rest and medicines may help or may need a small surgery. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, ENT & General Surgeon
