Hi. I have a "lump" the appeared on the back of my neck a few days ago. It is located at the base of my skull about an inch left of center. The lump is soft. It was very painful to touch or to move my head in any direction. It seems to swell during the day and reduces at night. Cold seems to to make it feel better. It is less painful now although the bump is very sensitive.I am abroad and may not be able to see a doctor for a week. Any suggestions would be welcome.
Hi, This is likely to be an infected sebaceous cyst. They are common in this area. Treatment is with antibiotics or surgical removal. I suggest you see a local doctor for antibiotics whilst abroad and then consult your own doctor when you get back who may recommend surgical removal. Continue with cold packs to relieve any soreness.  Chat Doctor.
