If it's puffy and red, go to the doctor, it can be infected. They can take care of it well enough so you might be in shape to camp this wkend, if you get in quick enough. I am the queen of ingrown toenails, I had surgery done because they were chronic (fRom like childhood). That wasn't fun either, you have to dig into the wound with a freakin stick for weeks for it to heal properly, it's insane. Maybe they do something better now with lasers or something, idk, my surgery (outpatient) was about 20 yrs ago.
