You can perform the Heimlich maneuver on yourself.

Few people realize that they don't need someone else to dislodge a piece of food from their throat.

Naman Mitruka explains how to perform the Heimlich on yourself:

1. Form a fist with your stronger hand below your rib cage and just above the navel. Place your other palm over the fist to push more firmly.

2. Drive your fist in and up in the diaphragm area (the top of your stomach) forcefully and repeat several times until the object that's stuck in your throat gets dislodged.
