You should get a second opinion. I hope that he ruled out a minor stroke. It may or may not have had anything to do with the drug you took, the timing may have been coincidental. A second opinion (or even third opinion) might clear things up or give you confidence in your diagnosis. Remember that doctors are just like the rest of us... they are human, make judgement calls and sometimes are off of their initial diagnosis. Good luck and I hope you feel better soon.....
