Levaquin and thyroid condition

I took Levaquin for a sinus infection about 8 months ago. While taking the course I began having heart palpatations, tremors, restlessness, muscle spasms, pain in my neck/throat and seriously strange hallucinations. I called my doctor and asked if this was a common reaction to the antibiotic and he said no but thought it may be a thyroid condition. I spent time exploring metabolic possibilities etc. and the blood work came up normal. Most of the side effects disappeared but my eye sight never recovered (I became super sensitive to light) and I occasionally suffer from heart palpatations, tremors, migraines... all of which I never had prior to treatment. Recently I had a sinusitus flare up and was prescribed Levaquin again... after the FIRST dose my tongue swelled, tremors, heart palpatations, hallucinations PLUS the entire left side of my body went numb. I knew immediately to discontinue when I researched it myself and found most of the CNS complaints/side effects were mine as well. It has been over 6 weeks since the last exposure and I still am suffering from heart arhythmia, head aches and my sight is a major concern. I would love to know if there was some way to treat these symptoms/effects efficiently since it seems most last for quite some time?
