Thank you for writing in to Ask the Expert.
You say that this lump has only just occurred, so from what you describe it sounds like this lump could be due to the presence of a blocked hair follicle or sebaceous cyst.
We enclose some details of what these lumps caused by these minor ailments look like:
Sebaceous Cysts are a general categorization for two types of cysts that effect the skin- Epidermoid cysts or Pilar Cysts.
There are other causes to of lumps and bumps on the head but these are usually associated with head injury, fatty deposits or skin changes due to ageing or sun exposure.
We would suggest that because this lump has happened suddenly, and is painful to touch, that you get reviewed by your GP as soon as possible.
Your GP will be able to assess the cause of this painful lump and will if necessary treat it by the appropriate means.
Depending on the cause of the lump treatment may include antibiotics or minor surgery within a minor surgery clinic held at a local GP facility.
We hope this gives you some reassurance.
