I Have Had Pretty Sever Damage To My Vocal Cords.it

I have had pretty sever damage to my vocal cords.it does not help that I barely talk to anyone in more than a very low bordering on whispered voice.when I do try to have more than a five minute conversation my throat becomes scratch and my voice gets straiened again. Is this simply due to not useing my voice? I have attempted to draw out conversations to ease the discomfort but sometimes it gets sore LIKE a sore throat but without the being sick that follows. Is there anything natural I can take to help this?
