So, I suddenly find myself with this odd metalic taste in one side of my mouth. Tastes like copper. Went to go brush my teeth after noticing this, and it seems that my gums are bleeding in one part of my mouth (where the taste is coming from).
Any ideas on what this could be? Am I slowly turning into a Tin Man like the one from Wizard of Oz? Should I invest in a can of WD-40 to carry with me?
