That bump in the night

Whenever there is a bump in the night, its usually me. I tend to bump things when I get too fat. When I walk through chairs or tables, my internal navigational system would have adjusted for the path and course corrected itself. Unfortunately, the blubber department did not update everyone that it has accumulated 50Kg of fat...

And so, this is the bump for the night

Which was not a problem until I started to scratch at
it and accidentally dug out what seemed to be a
bloated hair follicle...
