i sprained my ankle in san francisco...
(hey! that might make a good song!)
3 weeks. still recovering...
the ligament is stretched beyond normal range,
resulting in a tear, spraining the ankle.
grades of sprain
grade 1 - minor swelling/pain for 1-2 weeks
grade 2 - more swelling/pain for 4-6 weeks
grade 3 - worse swelling/pain for 8-12 weeks
correct healing techniques are required for full recovery
RICE right away is an important part
and obtain advice from a doctor
physical therapy and exercise
will reduce swelling/pain, and strengthen ankle muscles
incorrect treatment is case for future issues
and increased chance of re-injury
