Mucinex d symptoms and conditions

I'm a 31 female. I was diagnosed with bronchitis/sinusitis on 5/28 and was given Biaxin which did not help. I was instructed to return to the doctor if I did not feel better within 2 to 3 days. On Monday 6/2 I returned to the doctors per instructions because I was not feeling better. He switched me to Levaquin 500mg 1 a day. I took Levaquin at 8pm Monday evening. I was unable to sleep that evening so I researched the medication the following morning and saw that Insomnia was a side effect. Starting at 10am today 6/6 I begun severe hip pain in my right hip. I called the doctor and they instructed me to stop taking the medicine for 24 hours and begin treatment again if the pain reduces. After reading this information I'm now reluctant to start "if" the pain subsides.
