Hi,
Thank you for posting your query.
The lump could be a
hematoma (blood collection) or an
abscess. However, the abscess would be warm and tender to touch. So, the most likely cause can be a resolving hematoma, which usually gets better on its own. However, a doctor's examination would confirm the diagnosis.
Please get back if you require any additional information.
Best wishes,
