I pondered posting this in Sporner's Corner but no photo for obvious reasons so am appealing here for advice. (And I know that this isn't a substitute for a medical opinion).
Yesterday a really painful lump appeared very near my bum. Apparently it was weeping a little last night. It's really painful today, with a constant ache that gets worse when I'm sitting down. I'm fairly sure it's an abscess but I can't get to a walk in centre until Monday afternoon (only A&E here and it's neither) or possibly Thursday given Christmas.
a) how urgent is it to get seen (can it wait until Thursday or is my bum going to go septic if I don't get antibiotics), and b) what can I do to make it less painful until I'm seen?
