I had my thyroid removed after 3 bouts of Graves’ disease over 30 years and I became allergic to one medication and the other knocked out my immune system so my white cells were gone. I was worried about the nerve for my voice but was happy I could speak ok after but it did take time as my throat was so sore I could not swallow tablets unless crushed for weeks after. It takes time to heal and there is some good advice given by others. Take care and be patient but seek advice in a month to relieve any stress . My surgeon also told me about help with voice if I needed it but give it time. Let us know how things are going in a months time please. Best wishes and rest your voice .
