Feels like contraction or expansion inside head, common before sleeping or if disturbed during sleep. Some times this symptom combined with weakness in hands and legs(feels slight burning sensation when I put cold water during this period) Persistence from 2 weeks.( once appeared 6 months ago and cured automatically). Hiccups also happens some times during this episode. The symptoms tend to disappear when I make myself busy with people and not to think about this. ( but it has become too difficult not to think about it). I did full health check up. BP, ecg, urine test and all sugar tests are normal. My height 184cm and weight 75kg. I have some personal stress and work related stress. I no longer feel normal and face difficult to concentrate on life and work. I was advised ESOMAC D40, MECBENN, IBUPROFEN 400 AND CLONAZPEAM 0.2 tablets for 10 days, but situation is not improved. No alcohol or smoking habits. I have quit tea, coffee and following timely intake of food.
