Hello and welcome to HCM,
Swelling on back can be due to many causes.
Hot and itchy lesion suggests an infectious pathology.
Difficulty in moving the neck in different directions,
stiffness and pain can be due to muscle spasm or muscle stiffness secondary to the inflammatory process.
An aspiration cytology of the lesion needs to be done.
In this investigation, the cells are aspirated from the swelling, spread on slide, stained and examined microscopically.
This investigation will determine the origin of lesion, its nature- inflammatory, non-neoplastic or neoplastic.
Further management can be planned according to the results of the investigations.
Thanks and take care
Dr Shailja P Wahal
