High school football can injure you very badly. One of the worst ones is concussions. Concussions are a brain injury caused by a blow to the head. They can result in physical and mental symptoms such as, headache, dizziness, and forgetfulness. The symptoms typically go away in 10 days and do not last for more than several months.
Football players can also have ligament sprains. Ligament sprains are the tearing or stretching of ligaments. A mild sprain can get you to full mobility within 3 to 8 weeks. A severe sprain can take months for a full recovery.
