Hello and welcome to e health forum. â
It is difficult to analyse a skin condition without a complete medical history and a visual âââexamination of ââthe lesion.
Lumps seen in the body can be due to causes including - common benign conditions as well as severe âââconditions like ÂÂcancer and chronic diseases.
But symptoms like persistent fever, weight loss, night ââsweats along with multiple enlarged, painless lymph âânodes may indicate conditions like lymphoma or ââcancerâ. â
In your case, the lump in your neck could be a enlarged thyroid gland, a lymph node or a thyroglossal cyst. A ultrasound will definitely help in providing more infomation, as to the cause of the lump.
Hence you may continue to work with your doctors for a proper diagnosis and treatment.
