Tell me your thoughts on this and whether or not I should be concerned about this. About a week ago, I got a blood test done at the hosptial as part of a pre-op testing. After the blood test, my arm was more sore than usual, I felt like I couldn't bend it. Now, a week later, I have this huge bruise near the site of where the blood was drawn. I also have these pink/red lines, like bruise lines I guess they're called, they look like scratches, but are part of the bruise, and they are from the bruise up to above my elbow. They are vertical lines. Since I noticed them a few days ago, they haven't progressed and I haven't seen anymore. Also, that arm has been extremely sore, I can't do anything strenuous with it or lay on it or anything like that. I have never had this kind of reaction to a blood test before, as a matter of fact, I had a blood test about two weeks before this one, and it didn't even bruise. Since this was done in a hospital, I am confident that the needle was sterile. Is this normal at all, especially with these lines that extend up my arm? I really don't feel like going to yet another doctor for something that is normal, as I am tired of running back and forth to the doctor as this point. Could it be a skin infection, even though it was a blood test with sterile needle? And if it was blood poisioning, wouldn't I have noticed by now? Is this something I need to worry about? Thanks in advance.
