Hello Our voice, though formed in our voice box, is modified as it passes through our Nose and Sinuses. SO , if you have a bad cold , it will change the voice Medical treatment for your cold would be helpful , when it flairs up At present though , you don t have a cold and based on the information you gave, this problem sounds like Laryngitis. This is an inflammation of your voice box, which can occur because of many reasons - infection , smoking , excessive acidity etc. This problem can increase because of poor hydration , and excessive voice usage So the first step is to increase water intake , don t smoke , give your voice rest ( speak sparingly and don t whisper or shout ) If the problem persists you need to visit an ENT doctor ( preferably who specialises in voice problems ) You may get a laryngoscopy done ( a camera examination of you voice box ) to confirm the problem and start the appropriate treatment Thank you
