My 2 year old Veiled yemen has had a little white lump on his casque for about 2 weeks now, it doesnt look like its under the skin more on top at first it looked dry with a red/blackish dot on top, now its just a white lump. Hes acting normal and it doesnt seem to hurt him. its fairly small and looks fleshy. if anyone knows what this could be please let me know.
