I'm still undergoing process of diagnosis. I've had tingling before, but only on the left side. Now, it's on both sides. It starts going down the side of my head and down through my right or left arm. Then my arm becomes numb, like I'm coming off of novocaine. When the numbness comes, my arm then becomes weak and normal strength is diminished. I can't lift things. I can't even write.
The weird part is that while I have tingling, I'll get the sensation of cold water being poured down the inside of my arm. Then, I'll get goosebumps all down the arm, but the arm that doesn't tingle, is completely normal. No goosebumps. Has this ever happened to anyone? How can I get goosebumps down one arm, but not the other? What does it mean?
