What Causes Lumps In The Arm?

I have a spot under my arm. When my arm is down it is in the crease, when it is up it is in the corner. It hurts, I have squeezed it and some white substance came out, what came out after that was just a fluid. It is still there do you have any ideas? I suspect a hair follicle infection.

Hello! Welcome to HealthCareMagic.
This can be a sebaceous cyst.
Punctum is the hallmark i.e. a black dot seen over the intact lump.
It should always be removed completely along with its capsule under local anaesthesia by the doctor.
If the cyst wall remains behind then the recurrence is inevitable.
Get examined by your doctor.
Hope this information is useful.
Thanks. Regards.
