If you have injured your ankle, here are some steps you can take to manage the injury:

1. Rest: It is important to rest your ankle and avoid putting weight on it. Use crutches if necessary to help you move around without putting weight on the injured ankle.
2. Ice: Apply ice to the injured area for 15-20 minutes at a time, several times a day, to help reduce swelling and pain. Use a cold pack or wrap ice in a towel.
3. Compression: Wrap the injured ankle with a compression bandage to help reduce swelling and provide support. Be sure not to wrap it too tightly, as this can impede blood flow.
4. Elevation: Elevate your ankle above the level of your heart as much as possible to help reduce swelling.
5. Pain relief: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help relieve pain and reduce inflammation.
6. Seek medical attention: If you have severe pain, swelling, or difficulty bearing weight on your ankle, or if you suspect a more serious injury such as a fracture or dislocation, seek medical attention right away.

It is important to follow these steps to help manage your ankle injury and prevent further damage. 

Here are some guidelines to help you determine when to see a doctor:

1. Severe pain: If you experience severe pain in your ankle, it is recommended to see a doctor as soon as possible.
2. Swelling and bruising: If you have significant swelling and bruising in the ankle area, it is also a good idea to seek medical attention.
3. Inability to bear weight: If you are unable to put any weight on your ankle, it may be a sign of a more serious injury, and you should see a doctor.
4. Deformity: If you notice a visible deformity in your ankle, such as a bone sticking out or your ankle appearing crooked, it is important to seek medical attention immediately.
5. Previous injuries: If you have had previous ankle injuries or ankle instability, it is recommended to seek medical attention to ensure proper treatment and to prevent further damage.
6. Delayed improvement: If you have tried home remedies such as rest, ice, compression, and elevation and your symptoms have not improved after a few days, it may be time to see a doctor.

However, if you are unsure about the severity of your injury or are not seeing improvement after a few days, it is recommended to consult with a healthcare professional. They can provide a proper diagnosis and recommend further treatment if necessary. It is important to take ankle injuries seriously as they can lead to long-term problems if not properly treated. If you are unsure whether you need to see a doctor, it is always better to err on the side of caution and seek medical attention.
