Why hasnt, and when will my voice come back?!

Im a 31 yr old female, i became sick with pnemonia and broncitis on the 23rd of Jan, i was put on amoxicillin, and prednisone. Most symptoms have gone away, except for some mild sinus congestion, swollen glands in the neck, and sore throat. I lost my voice (not completely, but very hoarse) on the 29th of january (i assumed it was from all the coughing i did during the pnemonia). I went back to the doc an she put me on another antibiotic, cefdinir. still no change. So she put me on yet another antibiotic, augmentin. After a few days of taking the augmentin i began having severe itching and what seemed to be acne on my cheeks. A couple more days after that, i realized it wasnt acne, it was a rash that spread all over my face. It drove me crazy with itching. So the doc says its an allergic reaction to the augmentin. She told me to stop taking it.

Its now Feb 18th, and my voice hasnt come back, if anything its gotten worse (its very hoarse, quiet and sqeeky at times, it takes alot of effort to form a full sentence). My cough ended weeks ago. I still have a sore throat, ive been extremely tired. My body aches, and I have noticed my breasts are very tender. The only time my breasts have been this tender was when i was pregnant. I have had two periods since the last time i had sex. Just to be on the safe side, I took a pregnancy test a couple days ago, it was Negative. My doctor is referring me to an ear nose throat doctor, so im just waiting for that appointment.

Does anyone have any idea what could be causing all these symptoms, or how long it will be till my voice is back to normal?
