Thank you for posting your query.
The swelling most likely is a hematoma
, which has not yet completely resolved. The skin color changes may not be so obvious always. I would request you to upload a photograph of the swelling to help us reach a better diagnosis.
Also, it is safe to take a 10-hour bus journey and there is no risk of dislodging the clot. This clot is not in the veins but in the soft tissue
. Clot in the vein can get dislodged, and cause problems.
I hope it helps.
Please get back if you require any additional information.
