Welcome in H.C.M. for Consultation.
I have gone through your query regarding swollen face on one side ,and on the same side enlarge and tender lymph behind the ear. As you said this happen twice in last three months.
Considering all aspects of your complaints it appears that swelling on face and enlarged lymph node
are involve in same pathology. Depending on the structures on face possibilities of swelling is as under-
(1) Recurrent furunculosis
or sebaceous cyst.
(2) Parotid lump ( mumps)
(3) Lump from ramus of mandible.
(4) growth of maxilla
To confirm this I will advice you following basic investigations-
(2) C.T.scan of paranasal sinuses
(3) X-Ray Mandible OPG.
(4) FNAC from lymph node.
(5) Blood- CBC, ESR, blood sugar- F & P.P.,
Thorough examination and clinical co- relation of inferences of investigations will guide us to make proper diagnosis which can be plan for treatment.
