Hi, thanks for writing to HCM.
From the description, I feel that you might have developed as SOFT TISSUE HEMATOMA
secondary to trauma.
If you are able to walk normally, then a fracture
is unlikely and I dont think you need to rush to the ER. But if you are worried and concerned, then go ahead.
The initial management of the Hematoma is as follows -
* Rest to the injured part and dont involve in putting additional strain on the injured tissues.
* Ice packing should be applied for about 20 minutes once in every 2 hours.
* Use elastic compression bandage around the swollen area
* Elevation of the limb
& anti inflammatory medications
Hope this information is helpful. Good day
