Hi..
Can understand your concern..
As per your complain the swelling has occurred due to trauma to the soft tissues causing inflammation and the swelling occurs due to formation of inflammatory exudate as well as rupture of minor blood vessels causing spillage of the blood into the soft tissues causing haematoma formation,bruising and swelling..
Although you have got the stitches placed but you need to take a course of antibiotics to prevent any infections as well as oral steroid therapy to reduce inflammation and swelling..
For pain you can take inflammatory painkillers like Advil/
Ibuprofen..
You can apply alternate warm(not hot) and cold compresses alternatively for faster healing..
If there is open wound you should apply antiseptic
ointments like
soframycin or
neosporin over it to prevent bacterial proliferation and infection over it..
Take a
soft diet and avoid spicy and hot food to prevent irritation of lips..
It will take some time but gradually the swelling and pain will subside..
Hope this information helps..
