So I've developed this growth on my cawk.... Its approx .9 centimetres in diametre. And @.3 cm in height. It has a hardened-looking core at roughly the centre of the inflamed area. Picture a miniature Sabot round.Now picture it on my cawk surrouded by a livid swelling.This core is slightly discoloured. Not quite salmon, but almost rotting-mango toned. Discolouration is strictly localised to the "head" and does not present in surrounding tissue. Also there is a fruity odor with hints of sulpher and almond. Can you help me? it really, really itches..
