Packing for a trip to Walt Disney World in December or January means being prepared for anything. Check the extended forecast before you leave. Bring along a sweatshirt or light jacket, and dress in layers that you can remove as the temperature warms up through the day.
Injury of a Muscle or Tendon. A damaged tendon or muscle can be the main culprit behind the swollen bump on the back of the neck. Muscles and tendons keep the body in shape and when one is injured or pulled, the muscle moves from its original position. The damaged part of the muscle sticks out, which forms the lump.
Causes of a Lump on Back of the Neck. 1. Injury to a muscle or tendon, from an accident or strenuous movement, can result in a lump on the back of the neck.
