[|Human|] Hi,I have noticed  a hard lump on my head (towards the back, left). It is not moveable. I first noticed it late last year (November) then forgot about it again.  It is still there. Should I see a doctor to get it checked out?  I also suffer from headaches, and heavy head feeling, constant tiredness and lack of energy.  Thank you.
[|AI|]  HI. The hard, non-mobile lump may not be the reason for your symptoms. But to make this sure you should consult a Doctor get the CT /MRI of the brains and the skull bone to confirm the relation of the lump with the symptoms. The Doctor would also check for the other probable reason of your headache like high BP, power in all the limbs, pupils etc. This clinical examination has no alternative and should be checked. Waiting for the reports.
