I met with an accident three month ago, I got hurt near right ear on head, no bleeding, I got CT scan, CT skull and all was normal. But i still feel discomforts, and Puffing in the head from right ear to back head and  makes me sleepy. What test should I consider to know the exact reason and my ailment so that i can get right and best treatment. Please suggest me the right test, and diagonosis. I went to a doctor and he prescribed me antiepileptic medicine without any tests. However this medicines makes me relax as soon as i take this medicines. After discontinuing medicines the same symptoms starts after 12 hours.
