hi thank you ..... I have a bump back of my head it some times leaks ..... I have gone for cat scan , blood work all comes back .I feel something in there and is not right what should I do . YYYY@YYYY thank you look forward to hearing back from you.
Not to worry much as this is benign condition like sebaceous cyst; take care not to get infected there!if really worries you can go for an FNAC test for confirmation all the best!
