Lost my voice

since monday, i have had a very hoarse voice which at times is inaudible.  not ideal being a medical secretary but never mind.

i had a 5k on sunday and had a thumping headache by the time i got home.  took meds and woke up with migraine at 3am; took more meds.  felt better by evening (although still slightly queasy.)

i feel absolutely fine (apart from being a bit tired but i have a 3 year old so that comes with the territory) and i have no sore throat or inklings of a cold but still the voice of a 60 a day smoker (i don't smoke.)

any suggestions?
