I am 19 years old male, having problem with body temperature. After vomiting for 2 times 2 days ago and then after that vomit i got some hot feeling on touching my skin. But the thermometer reads a normal temperature , sometimes lower than normal also. My hands are also cold sometimes. But I dont feel cold or feeverish just hot feeling on skin. My pulse count is also normal 72 beats per minute. What is causing this? It occurs only in morning after waking up from sleep.
