Just noticed a lump in on the left side of my jaw where the jaws meet.  It is small, not painful.  I was diagnosed with whooping cough and pneumonia on 1/6/12 and placed on antibotics.  I still have a cough and cold like symptoms.  Is this something I should get checked?
Yes u get checked.it probably a lymph node enlargement may be due to some oral cavity infection or parotid gland enlargement or irregular, inadequate antibiotics taken past, u should undergo investigation FNAC to rule out
