This is a strange question, but can RA cause popped blood vessels in your finger? I was sitting here reading and all of a sudden my finger started stinging and hurting like crazy. I looked down thinking something had bitten me and saw that my finger is swollen and was starting to turn purple. Then it dawned on me that it was a broken blood vessel. It doesn't hurt now, unless I bump it. Any thoughts, or is this just a random act of weirdness on my body's part.
