I have lost my voice and this morning i coughed up some hard green stuff. i try and cough anything else up but nothing. what should i do?

Clinic in 24 hrs : If you are having a fever with temp >101, difficulty breathing, shakes, body aches or chills, you should go to a clinic and be seen. If you are otherwise healthy and on no regular medications, it is reasonable for you to just stay hydrated by drinking plenty of fluids. Use otc tylenol (acetaminophen) for pain and see if it resolves as this is quite likely a viral illness that will be self limited.

Stop "trying": You will cough when something is in the right place to bring it up. Forced attempts at cough can cause pain and small bleeding. Try using a vaporizer (steam best if no risk of burns to small kids / yourself) to moisturize air and loosen mucus (=green stuff) as well as help your vocal cords. See your dr if not improving in 2-3 days.
