Since the afternoon/evening of Feb. 12th I've had a mystery oval bruised area on my inside right forearm. Abput 5 inches long and 3 inches at the widest. It's a mystery because I can't think of any impact that would have produced the bruise. It's slow to heal up, at least it doesn't ache, nor is it especially tender to the touch. Weirdly, there's a more tender spot to the right that isn't bruised.
