Hi, thanks for writing to HCM.
The description suggests that you sustained only SOFT TISSUE CONTUSION
The initial management is as follows -
* Rest to the injured part and don't involve in activities which puts 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
& anti inflammatory medications as needed
If your symptoms are not resolving with the above measures, consult your treating physician.
Hope this information is helpful. Good day
