Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain swelling of the
salivary gland on the right side of face with knots that are hard seems to be probably due to swollen salivary gland is indicating towards infection in the salivary gland and is probably due to bacterial infection...
Swelling will subside once the infection will be treated..
For this first of all investigation for confirmation of cause of infection has to be done and
MRI scan and saliva culture has to be done for diagnosis..
He can be advised a course of antibiotics like
Amoxicillin , cephexime etc along with anti inflammatory painkiller like
Ibuprofen..
Doing cool compresses over the swelling can help..
Chew sugar free chewing gums to stimulate saliva flow and also drink plenty of water..
Massage the glands gently with fingers..
Hope this information helps..
Thanks and regards..
