[|Human|] Ive had a small lump on the back of my head for a couple of years.  3 weeks ago I scratched it and it opened up.  There was a white, horseradish texture substance in it.  Since then it has been draining.  It has dry, hard, flakes of skin around it.  The past few days it has been very sore.  The right side nodule on the back of my head, just below the hairline, now has a lump on it and my throat is sore.  I feel a little disoriented, also.
[|AI|]  Hi, The lump you describe is most likely to be a sebaceous cyst. This is not serious, and they are commonly found on the scalp. The soreness may indicate that it is infected. I suggest you see your doctor who will be able to assess whether you need antibiotics. Surgical removal may be an option. The second lump you mention is likely to be a lymph node which is related to your sore throat. This will disappear when your sore throat is better.  Chat Doctor.
