I am a 31 year old mother of 3 in generally good health. About 6 months ago I noticed a small lump on the top of my head that was sore to the touch. I am certain this was not caused by trauma. Over the past 6months the lump has grown both in diameter and height. It is hard and unmovable and at this point is similar in size to half a walnut. I have also been experiencing mild to severe headaches that have been increasing in frequency and are now daily occurrences. The headaches come with a sensitivity to noise. i have also been experiencing what I can only describe as a personality change as I seem to have very little patience and feel like I am "snapping" at everyone. I went to see my PCP and she examined the lump, palpitated the lump, and stated it is not a cyst. She then said I should have it removed and referred me to a general surgeon. i asked about further testing such as CT scan, MRI, or ultrasound and I was told they would only confirm there was a lump between the scalp and the skull and we already know that.
At this point I am unwilling to immediately submit to invasive surgery on my head without some additional information. Please I would appreciate any additional input or suggestions.
