You would need to take your gerbil into to see a Veterinarian to check him or her out. It could be a cancerous lump, or a fatty tumor, etc. but only your Vet would be able to diagnose this.
go to the vet

It could actually be a boil, but if you are worried, then see your doctor.
A lump on the back of your head that is itchy may be from an inset bite. If the lump does not go away, visit a doctor.
gerbils wornt discovered back then
you must wear protective clothing, gloves and goggles. Firstly place the gerbil in a clamp with its hands tied behind its back and always use a gerbil muzzle so not to be bitten at any stage. Now its safe to cut your Gerbil.

Nothing. The nail will grow back on its own.

A smelly lump on the back of the head may be an infected abscess. It could also be a sebaceous cyst.
you should really take it to the vet. i don't think it is a good idea to put the injured gerbil back in the cage though.
go to a docter
