Today at work i was pouring soup into a cup when it spilt onto my thumb and just above. i out it under cool water straight away but it was still burni?

Yes?: Given the scenario you described, a burn is possible. If the skin is red and tender to touch, but the top layer of the skin is preserved, it is likely a simple first-degree burn that will heal within the next few days. If the skin is broken or there are underlying tissue exposed, I would get it seen by your doctor. Otherwise, cold water will soothe it, and some simple burn ointment will help.
