I had blood drawn on Tuesday, and only yesterday did a large bruise appear in the area, and my arm , shoulder , and back on that side now feel very sore. I would not think that these were related, except the bruise and the pain both appeared at the same time, and I have not done anything else since that time that I could attribute both of these symptoms to. I have had blood drawn many times, and have never experiences these issues. Is this normal, or are these symptems of an issue?
