M jones symptoms and conditions

I was prescribed Levaquin by my Dr. for a sinus infection. There were 10 pills and I was to take one a day. No one mentioned any of the side effects or drug interactions except to not take antacids within 2 hours of taking the meds. During the coarse of me taking the medication I began having substernal chest pains which I thought was just horrible heart burn, but it got so bad that I woke up screaming multiple nights from the pain. I also started having pain in my ankles, legs and especially my knees. The pain in my knees gets so bad that I think my knee caps are going to shatter when I walk especially when going down the stairs. I didn't know any of the drug interactions and my father in law who is a physical therapist has always advised me to take ibuprofen for muscle and joint pain so that's what I did, but little did I know that was only increasing the effects on my central nervous system. I am also experiencing bouts of nausea, confusion, light headedness, difficulty sleeping, anxiety and I actually thought I was having a mental breakdown.. I was freaking out on my husband and very depressed even having suicidal thoughts. It wasn't until my mother randomly mentioned that she had heard about the FDA issuing the Black Box warning that I connected the dots and had already finished the meds. I called my doctor's office right away and was told that the symptoms I am having are not side effects of the medicine. Maybe the Dr. doesn't listen to the news either.
