[|Human|] I have been bothered at night with a stiff neck...to the point it wakes me up (left side) and today I noticed that there is a lump on the back of my head, tender to the touch. If I put my palm on my left ear, I can cover the tender area with the middle to end of my fingers. It is quite tender and the more I touch it the more my neck aches.
[|AI|]  Thanks for sharing your health concern with us!well, it is just an infected sebaceous cyst or an enlarged lymph node and not to worry much for this. You have to press ice-cubes or cold compress and take some broad-spectrum antibiotics like erythromycin; if not relieving within 7 days then consult some surgeon for aspiration /excision of the material inside; never poke it as this may invite infection! All the best!
