Simmer is a term used when something is to be cooked over a very low heat, generally for an extended amount of time. Normally, you bring something just to a boil and then turn down the heat to low (or possibly medium low) so that it continues to simmer. The term simmer is only used when there is liquid involved in your recipe. Simmer is most often used for making some type of homemade sauce or stew.
Ankle sprains take an average of 6 weeks to heal but can take can up to 4 months, depending on the severity. An ankle brace, air stirrup, hiking boots, or other form of ankle support should be worn during this time to protect the ligaments.

Recovery time for ankle injuries varies based on the severity, but for a grade 2 sprain requiring crutches, it will typically take 5 to 10 weeks until the joint is fully healed. You will want to use crutches for the first 4 to 8 weeks, longer if your doctor recommends to. For a grade 3 sprain, the joint may be unusable for 3 to 6 months and perhaps longer if the injury is serious. Crutches become absolutely necessary for the entirety of the healing process for an injury of this severity.
