I was a soprano. 3 weeks ago, I came down with a cold, starting with s sore throat. Did not miss a day of work, since I am a teacher. Did not lose my voice neither. Got a prescription of Amoxicillin, 500 mg., and took it for a week and started to cough. Ever since then, I can't even hit
the lowest note. I can talk but can't sing at all. Anything I should do to gain back my singing voice?
