It seems from the history that you had a injury
to the nose and following which you are having swelling in the area between eye brows associated with pain.
This indicates hematoma
because of collection of blood in the layers of skin as a result of impact of trauma.
The treatment is by use of antiinflammatory drugs and cold compression. Evaluation by tests like X ray
is required to look for fracture
of the underlying bone.
Hence I advice you to consult your doctor for examination and treatment accordingly.
