Gpm, in your second post you mentioned a tumour 'discharge', is this separate from the bleeding caused by licking?

I've been looking at rubrics like Itching, effects after scratching. Drawing blood. Denudation. As well as Skin, tumour <just a general pathology definition for any number of swellings, nothing sinister> and the remedies that appear most are Calc carb, Lach, Lyc, Merc, Sulphur.
Obviously it's hard to know why Seabert licks the area so compulsively, whether it's an itch cycle or it burns or smarts. Another "must scratch till it's raw" remedy is Graphites when attended with a gooey discharge.

Anyway, given that he has had success doing an 8 inch poo, crikey, anybody would hafta feel a bit better after that ! , so let's hope he's feeling more of his normal self today.
