'Nacken' (neck/nape) is often used in connection with pain or tension. Typical phrases are 'Schmerzen im Nacken haben' (to have neck pain) or 'der Nacken ist verspannt' (the neck is tense).
Mein Nacken ist vom vielen Sitzen total verspannt.
My neck is completely tense from sitting so much.
The idiom 'jemandem im Nacken sitzen' (to breathe down someone's neck) means to put someone under pressure or to constantly check on them. The person who is under pressure is in the dative.
Mein Chef sitzt mir wegen des Projekts ständig im Nacken.
My boss is constantly breathing down my neck about the project.
You can recognize the figurative meaning from the fact that the subject of the sentence is often an abstract thing (e.g., a deadline, fear) or a person who is applying pressure. The literal meaning is illogical here.
Die Angst vor der Prüfung sitzt ihm im Nacken.
The fear of the exam is breathing down his neck.
neck / throat
'der Hals' and 'der Nacken' both belong to the area of the body between the head and the upper body. 'Der Hals' is the general term for this whole area and can especially refer to the front. 'Der Nacken' is more specific: it means the back of the neck, where the head and back meet. The words can be confused because the nape is part of the neck area. For a sore throat, swallowing, or speaking, you would more likely say 'Hals'; for tension at the back, you say 'Nacken'.

After eight hours at the computer, Lena's neck is completely tense.
