I am having some wiered symptoms from last few weeks. I suddenly start feeling that everything around me is moving the same way as the fainting person feels but I remain conscious. At this point my heartbeat gets fast and my I feel like my head is getting tightened. Last night I was having a sound sleep and I suddenly woke up because I felt my head numb. My lips, eyes and everything on my head was numb and I felt a tingling sensation on my lips. Talking about the same night, every time I slept I was forced to wake up with this numbness in the middle of the night. As a result I couldn't sleep the whole night. I consulted a doctor here and performed C T scan. Everything was normal. I really want to know why all this is happening to me if the test came out normal.
