Levaquin and ibuprophen

I have had an extremely stubborn sinus/respiratory infection for around 12 weeks or so. Weeks ago I finished a round of antibiotics (Doxycycline (sp?)) without much improvement. Went to ENT and he prescribed Levaquin 500mg once daily for 21 days. I have been on this med for about 14 or 15 days. Sinuses are some better but I don't think it is all gone. Interestingly though, about 3 or 4 days ago ALL of my joints began hurting...all of a sudden. I have had a really sore shoulder for about a week, maybe more, that really isn't getting better. How bizarre that this is the site I found. It must be the meds. It is Friday 11/30, 5:15, of course so I can't call them now. I have an appointment on Tuesday and I will assertively and aggressively inquire about this. This is pretty scary. If I learn something new I will gladly post it here--but I truly expect to be told it is not the Levaquin...

I started on Levaquin for a sinus infection on Friday and by Sunday evening have the most unbearable pain in my feet, ankles, knees and hips. I could bearly move and took 3 ibuprophen and that took the pain away. I'll see if the pain comes back after the Ib wears off. I'm thinking it's the Levaquin.

I was prescribed Levaquin 500 mg for bronchial asthma on December 9, 2002. After the last dosage, I developed the worse shoulder discomfort ever. I have used compresses, ibuprophen and am in absolute misery. Nothing seems to help. What do I do.
