Hello,

Thanks for writing to us.

The swelling in the middle of the leg which your daughter seems like a hematoma or soft tissue swelling or an abscess.

A physical examination and X-ray will be helpful in making the diagnosis. It needs an early medical attention and will be best if you take her to an ER.

In the meanwhile, for symptomatic relief:
1. Give enough rest to your leg- do not bear weight on it.
2. Antibiotics and sometimes surgical drainage of the collection is needed.
3. Mild analgesics will help in pain.

I hope my answer and recommendations are adequate and helpful. Waiting for your further follow up queries if any.

Regards.
