question: Hi doctor, I am a college teacher. I feel fatigue and dizzy for past one year. I slept very late one night and the next day while taking class had a dizzy feeling for a second. I felt that my head was reeling and on that afternoon I took off. It did not happen again but I felt myself weak with less energy, as if I am about to fall if I do not sit somewhere. I was unable to stand or walk for a longtime because of fatigue and lack of energy. Nerves were twitching sometimes. I saw several doctors but I was unable to convey my symptoms properly. Sometimes, I get a sudden panic too, with increased heartbeat, dizziness, etc., with a frightful feeling that something is going to happen. An MRI scan was done which is alright. Hypertension, thyroid, and sugar tests were done and that too fine. The doctor said it may be a stress reaction and he gave a tablet for fatigue. After having that tablet for a while, fatigue was gone, but other symptoms of panic attack, occasional tiredness still continues. Please help.
