Hi, Thanks for using HCM.
Lump in front of ear could be lymph node enlargement. Any slight infection in ear or upper respiratory tract
can result in lymph node enlargement. Or other possible cause is salivary gland
enlargement. By examination of swelling we differentiate them.
Swelling by the side of neck could be lymph node or branchial cyst or thyroid nodule
examination of neck helpful in confirmation of diagnosis.
Hope this helps you.
