Some days I really do not understand how I could possibly have "no neurological conditions" when I have odd nerve sensations like I do. I always have tingling, random shooting pain, nerve firings..... But the strange ones I have had lately are 1) a sensation of a certain flavor. But not from my mouth. For example, the other day my arm felt like it had a metallic flavor. I don't know how else to describe it. 2) only when I am particularly warm or my leg muscles are warm from lots of walking I get a sensation of cold flowing down the inside of my legs. As if someone poured cold down my bones.
