Don't know about the buning in the head, but I was on it for a little while. At one point my body temp. went way up..it was about 70' outside and I was cleaning the birds cages and all of a sudden it felt like about 200' outside. This happened 3 times and I called the Dr. Very few people soo far have had this side effect. I quit the med. That was at he beginning of summer, and it is normal here to be about 100' outside, didn't want to struggle alll summer ect. Topamax for the most part didn't really help my head either. I was still needing to take the midrin.
