For the last 3 weeks I have been getting a feeling on the left side of my head ( travels from the top of my head, left side, down towards my temple) and it feels like it is the begining of pins and needles, (like something creeping down my head, but inside my head). It usually only lasts for 30 seconds to 1 minute and the left side of my head goes sort of numb and then a creeping feeling happens. It has been happening everyday now, atleast 10-15 times per day.
