Levaquin and strange sensations

I was taking Levaquin for a sinus infection. After taking the first dose of 750 mg, I noticed that I started having tingling and numbness in my hands and arms. After the second dose, I started feeling the same tingling and numbness in my arms, hands, and legs. Because I had been having severe headaches anyway, I started wondering if I had some kind of neurological problem and my headaches were linked to the strange sensations. However, I noticed that I didn't have any problems with my arms and legs until after I started taking Levaquin. Some of my other symptoms were: tightness in my neck muscles and sore muscles. I also remember seeing a flashing light from the corner of my left eye and floaters. I stopped taking Levaquin after just 2 doses because it began scaring me and I feared what might happen after my third dose. I can't afford to take any chances with my health. That's why I appreciate this post, and I see that I wasn't just imagining these side effects. Since I've stopped taking this medication I still have problems with my arms. They feel heavy like I've been lifting weights and the ache. A couple of times, I've had to take pain medicine for the pain in my arms because they've hurt so bad, it feels kind of like when you hit your funny bone and you try to figure out why they call it a "funny bone" because it's definitely not funny! My arms hurt so bad I couldn't lift them, and I could type or write so I just took some medicine (tremadol) and laid down. It's been weeks since I've taken levaquin, but I still I have sensations and aching and heaviness in my arms. Has anybody been off of Levaquin for a considerable amount of time and found that the symptoms go away? Please give me some hope! :) Thanks.
