The lump is maybe very slightly discolored a ruddier pink than normal but I can't tell if it's just from the prominence of the bump. If there is discoloration it isn't marked. It doesn't feel like fluid, more squishy/fatty than liquid. Again, much like the Ganglion cysts I've had. When I compare it to the other foot, it is located over a bone so that may be where the "hardness" I describe is from.
