Sine coming off the Topamax, I had a migraine that I couldn't not stop so i went to the ER. The wait was short, the nurse turned the light off for me, the doc came in (i've seen him before) he appologizes for having to shine the light in my eyes. Ask what I normally get and says "well with the meds. your own I think I'll give you a little more than the normal dose." "Hope you feel better, asked about topamax and kidney stones, and then the nurse brought the shot. 15 minutes later I went home, soon after migraine gone....wow. What a relief and miracle to have a good ER visit.
