Hello and welcome to HCM,
Hard immobile lump behind the ear could be due to lymph node enlargement.
Lymph node enlargement is most commonly due to infections and inflammations.
The swelling needs to be investigated.
Aspiration cytology is the first line investigation wherein a needle is inserted into the swelling.
The cells are spread onto a slide and stained with appropriate stains.
The cells are studied to know the origin and nature of the lesion.
Appropriate management can be done after relevant investigations.
Tiredness can be due to
anemia or low
hemoglobin.
Nights sweats is indicative of
tuberculosis.
Constant itching can be due to
skin allergy or any other skin lesion.
Thus, consult your primary healthcare provider for clinical assessment, relevant investigations and management.
Thanks and take care
Dr Shailja P Wahal
