I was in the hospital exactly one week ago with severe ear pain, tachycardia (165 BPM, resting rate 55) , and excessive BP (180 systolic). It was later discovered that my middle ear had ruptured due to infection, but that isn't the concern I'm posting about here today. While in the hospital, arterial blood was drawn (I assume for a gas chromatogram.) Immediately afterwards I had difficulty fully flexing my arm and hand. The next day, a sizable (4 in. diameter) bruise was present on my bicep. Over the past week it has grown slightly, and at this point I cannot flex my elbow past a range of approximately 80-100. It hurts, but I assume that's kind of a given. There is little swelling, but the bruise has not diminished at all; no yellow coloring, no reduction in size.
