The published signs of infection give you a checklist to hold against the toe.
Yes, and here is the list
An ingrown toenail can become infected. Cleveland Clinic says signs of an ingrown toenail infection include pain, redness, swelling and pus coming from your toe.
How to use the list
Read it as a set and check the toe against each item, not only the one that hurts most. Pain, redness, swelling and pus are all named, so a toe showing more than one of them is worth a call rather than another night of waiting.
If the nail has already been treated in the office, the MedlinePlus patient instructions after ingrown toenail removal are the paperwork to hold against the sheet your own office handed you. Cleveland Clinic also keeps a separate page on cellulitis, its symptoms and treatment for readers who want to compare descriptions.
What to confirm, and with whom
Ask the foot doctor which of the signs should trigger a call and how to reach the office when it is closed. Readers in Itasca should get that answer before the toe gets worse, not once it already has.
The verb that is easy to miss
The sentence says signs "include" those four. That wording does not claim the list is complete. If something else about the toe worries you, say so at the visit even when it is not on the list.
