Hello, I am a 20 year old male. I have been for the last month having on and off tingling on the TOTAL left side of my body. Not just arms and legs, but back, face, neck, and chest. The tingling would be on a scale of 1 to 10 a 3. It doesn't hurt, no loss of strength, no loss of coordination, no twitches or cramping (except left bicep, very rarely though) JUST TINGLING. I have been diagnosed with anxiety.
