Over the weekend I've developed what I think might be an umbilical hernia. It's very tender and I can feel a firmness above my belly button. I'm planning to call the GP tomorrow but wondering whether this is the sort of thing I should have checked asap (try to get a same day appointment) or if it's not so urgent and I could just take a routine appointment and be seen in within a couple of weeks. I don't have any signs that worry me about strangulation for example, just the fact that it's pretty sore.
Thank you x
