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 hard slap there has been traumatic
injury to the soft tissues of face and it is leading to inflamed and swollen tissues and swelling is also due to accumulation of inflammatory exudate in the area..
You need not to worry as the swelling will resolve gradually..
You can continue taking anti-inflammatory painkiller like
Ibuprofen or
Naproxen to reduce inflammation and swelling..
You can also continue doing cool compresses over the face and eye..
In case if there is
severe pain you can also apply numbing gel containing Lignocaine..
If there is bruising that is a sigh of ruptured blood vessels you can apply Thrombophob gel over the face but keep away from eye..
In case if the swelling does not resolve or you get increase in symptoms consult a General Physician and get evaluated and he can also advise you an x ray to check for any bony
fracture and treat you accordingly..
Hope this information helps..
Thanks and regards.
