Hi! A week ago I fell off my bike on the road and bruised my lip. There was a cut on the lip from the outer side (due to the road) and from the inner side (my tooth broke off and punctured the lip). The lip had swelled, and after 10 days it has now almost come back to normal except for a lump like thing inside. The lump is a little hard and a bit painful. The swelling is almost gone but this lump is causing trouble. Is it normal? Will it go away?
