I posted earlier in the week about how my doctor's office does these remarkably painful blood draws. I had one of them on Monday, with a tech who'd apparently been there for 20 years, and was in so much pain, I couldn't sleep that night. Finally, now that it's Saturday, it feels better.
But while I was in the shower this morning, I noticed an interesting bruise on my arm where they did the blood draw:
I've certainly had bruises from blood draws before, but this one baffled me. Why is there one central bruise then another one so high up? Does this offer any clues to what went wrong?
