I've had an incredibly sore naval. GP said yesterday it's a cyst, doesn't need antibiotics (thankfully as I can't take them really) and will go away. As it's so stupidly sore, she thought it could be irritating a nerve or something. Today it looks more puckered. There used to be a white circle at the top but now it's more of a puckered little hole. Does this mean it's going?!
