Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
A lump on the temple can be due 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 tends to resolve itself.
In your's case also, the lump seems to be due to a firm hematoma and you need not to worry as it will resolve gradually.
You should do alternate warm and cool compresses over the lump. Apply
Heparin gel as it helps in faster disintegration of the hematoma.
In case if it worsens,
consult a General Surgeon and get evaluated.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Honey Arora
