You have pain in your throat and back of neck but the lump on neck lies at the side of adam s apple is not hurting atall. No doubt you are having upper respiratory tract infection in the form of sore throat but the lump you felt in neck , just right of adam s apple is unlikely due to acute infection of throat because it is not painful. Therefore FNAC should be done to know the nature of the lump. Considering above facts it appears a thorough examination of throat and relevent investigations are necessary to pin point the diagnosis and that may be accordingly plan for treatment. I hope above discription answers your query. Regards.
