[|Human|] I have two hard lumps that are increasing in size and tenderness. The initial lump I notice about 4 months ago on the top, rear left side of my head. At first no one else could feel it but now it is more raised and about 1 inch by 2 inches. The second lump has appeared rapidly in the last 10 days at the top of left ear just beyond my hair line 1x1 inch. They are sore if medium to firm pressure is applied. In last couple of days the frequent headaches I have been getting seems to be localised to the left rear side of my head. I am not sure if me worrying is increasing my symptoms.
[|AI|]  Hi. Thanks for your query. Noted the history and understood the concerns. The commonest reasons for such lumps are infected sebaceous cysts as lipomas do not cause pain or tenderness even on high pressure. The headache on the same side can be explained by the involvement of the nerves either by pressure by the lumps on the nerves or stretch instigating the pain. I would advise you the following in such a situation:Consult a General Surgeon for clinical evaluation, examination and high resolution ultrasound to determine the cause and get these operated at an appropriate time to get rid of such lumps that are not a part of the body. You also get a histopathology examination.
