For the last few weeks I have had this sensation of pins and needles in my left ear. It is a transient feeling and happens approximately 2-3 times a day. Lately I have been noticing a cold sensation like someone is holding an ice cube to the inside of my ear during the pins and needles sensation. I haven't had any injuries or been feeling unwell prior to or during this time. If I could get some advice as to where to start for information or questions I should be asking my own MD so there isn't some thing overlooked I would really appreciate it.
