53rd symptoms and conditions

I was prescribed Z-Pak on Dec 31 2008 and it did help my bronchitis and pneumonia, however the side effects are horrible.....I still have a nagging cough but my breathing is better. I had to take gravol for three nights with this med as I was so nauseated and dizzy. Worse, I have agitated sleep and needing 10 to 12 hours of sleep because of awful sleep I am getting. I stared with diarrhea and hemorrhoids, and vaginal yeast infection. Losing urine with coughing which is due to my age and past pregnancies (53 years old), sore breasts and very sore nipples. Heavy period started 3 days ago.....which has shaken me...... as I went through menopause 11 years ago, yes 11 years ago! I had ringing in my right ear (never before) for 24 hours this week and have altered and less hearing in ear now). This is my 53rd birthday and I will call doctor Monday and see her asap. I am freaked out! Is this all from that med or do I have uterine cancer???
