Hello, Thanks for writing to us. Commonest cause of such lump in this region is enlarged lymph nodes. Other causes are thyroid nodule, glomus tumor, congenital cyst, lipoma or ectopic thyroid tissue etc. Since there are many causes, generally one needs a clinical evaluation and sonography to know underlying cause of lump. I would suggest getting this evaluated by a physician for an accurate diagnosis and appropriate management. You may get the X-ray of the area affected and FNAC (fine needle aspiration cytology) of lump under his/her guidance. Wishing you good health... Regards. Dr Saurabh Gupta.
