question: I have a blister on the side of my pointer finger just past the first knuckle from working with landscape tools. I cut it open to relieve pressure like I have done a thousand times and have kept it clean. I sqeezed it to much due to the irritation and soreness I attributed to a slight infection. now my finger is slightly swollen and is red/pink around the blister and over the last day the pink color has ran up my arm all the way to my armpit and I have slight pain or tightness up to my elbow. I have clidamyacin antibiotic from a infected tooth and took some hoping to slow the infection if that s what it is. what is happening and what actions should I take
