Hello there! I cut my hand yesterday accidentally with a razor. It was an old razor and it's a very small cut. However my whole hand is now hurting. The cut tingles and itches but also hurts at the same time. I've already cleaned the cut and have a band aid on it. But this isn't a normal cut because of the strange pain/ itchiness I am now feeling in my whole hand. What can I do? Please help? Thank you.
