For 2 days I have been losing my voice and I have bouts of uncontrollable dry coughing. It's causing the back of my throat to feel raw. What's wrong?

Possible infection. This could be due to a multitude of causes. Viral or bacterial infections could cause this. In some areas we are seeing a spike in whooping cough. Are your immunizations up to date? Certain medications can cause a dry cough. Probably a good idea to see your doctor if it persists, includes any breathing trouble or fevers.
