Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that due to
injury to the jaw and cheek along with cut on the cheek there has been inflammation of the soft tissues leading to swelling and lump formation..
There has also been traumatic injury to the blood vessels leading to accumulation of blood into the soft tissues leading to
Hematoma formation..
Hematoma is a harmless
tumor like mass formed due to spillage of blood from ruptured blood vessels leading to accumulation of blood into the soft tissues forming a lump..
At times the hematoma gets localized and encapsulated and forms a firm hard lump that can take a long time, say a few months to resolve, but it generally tend to resolve itself..
As of now you can do alternate warm and cool compresses over the lump/ swelling..
If it does not show signs of improvement in a month consult an Oral Surgeon and get evaluated and a clinical evaluation and investigations like
x ray,
MRI scan can help in diagnosis and will be treated accordingly..
Hope this information helps.
Thanks and regards.
