I just had surgery and they prescribed Levaquin 500mg. I have just started taken three days ago. My legs has sharp pains as well as my achilles. I have had numbness in my arms and hands. Also, minor confusion and comprehension. I DID NOT know all of this. The side effects on the labels does not say all these side effects on this bored. Now, I am worried after reading all of this. I am not putting another pill in my mouth. My doctor did not say " stop taking this at the sign of ..." This sounds like poison rather than a cure.
