[|Human|] Large lump on left side of forehead / hairline noticed this morning. Would say it is about 5 inches in length and 3 inched in width. Have noticed 5 to 6 pimples on hairline a couple days prior to this. Not sure if this is was caused by something irritating my skin. I do not have allergies or alergic reactions to anything that I know of, however 2 years ago I started have allergies around this time of year which may or may not be relevant.
[|AI|]  Welcome. I have gone through your query. It is difficult to comment on it without examination, so I would either suggest you to see doctor for examination and for exact diagnosis or upload the pictures here, I'll go through them, and provide you with specific advice. This might be sebaceous cyst or Desmond cyst, need to be examined to confirm. Kindly get it checked by general surgeon. Hope this helps. Take care
