[|Human|] 25 yo female with a sudden painful lump to right back of head, down on the bony area near the base of my skull. I just tilted my head back yesterday afternoon and noticed it. Very sore, increasing in pain also. My partner cant see anything (redness or otherwise) when he looks, but its hard because I have such thick hair. Also had shivering for a while overnight, and am running a low grade temp of 37.5 (celsius).
[|AI|]  Hello! Thank you for the query. Your symptoms are very characteristic for an abscess. Due to some inflammatory process pus gets accumulated in the mentioned area what gives hardness, pain, redness and fever. On the head, such abscess usually appears due to sebaceous cyst infection. Enlarged lymph node should be also considered. I suggest you to visit general surgeon as soon as possible. If it's an abscess, should be incised and Chat Doctor.  Otherwise, your symptoms won't get better. Hope this will help. Regards.
