I have developed a large soft lump on the back of my head.  Developed over the past two days and is soft tissue.  I have not fallen or had any trauma to cause this.  My doberman jumped up and hit me in the eye with his nose quite hard the day before i noticed it.  several of the lymph nodes below it are not hard and enlarged.  Any suggestionsIt is painful to the touch
Hi, This could be a sebaceous cyst. It is common to find them in this area. The injury from your dog has not caused it. If it is tender, you should see your doctor as it may be infected in which case antibiotics would be needed.  Chat Doctor.
