[|Human|] I experienced pain in lower back on left side, next day had severe pain around left shoulder up into neck. Had trouble turning head, later in the day I developed a pain in palm of left hand. A dark lump in vein appeared, felt tight and knotted. Later it settled and now looks like a bruise.
