I was carving a pumpkin and stabbed myself in my wrist on my left arm right below my thumb.  I went to the ER and got two stitches. Now, three days later, there is a large bruise from the bottom of my thumb on my same arm that goes down the middle of my wrist and it is about 3-4 inches long.  Is this normal?  Does it indicate more complication or possibly and infection?
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint due to getting stabbed there has been sharp injury to the soft tissue and also there seems to be injury to the blood vessels leading to spillage of blood into the soft tissues leading to bruising and you not to worry about it as gradually when the blood will disintegrate the bruising will also disappear. You can do alternate warm and cool compresses over the bruised area and also apply heparin containing gel like Thrombophob gel or other brands available at your local pharmacy as it will help in faster disintegration of the blood and bruising will resolve. You can also apply an antibiotic ointment at the site of cut to prevent infection. Hope this information helps. Thanks and regards.
