I had an accident with a fork that I had placed directly over the fire (mixed it with my eating fork) and ended up with severe burns on my lips and mouth. Due to covid-19 I didn't want to go to the doctor, so thinking it wasn't serious I applied a wet cloth for 10 minutes and then a baking soda paste. Both were really bad ideas. I didn't have any pain before, but after the baking soda I was about to cry.
I'm allergic to NSAIDs so I couldn't take any of that either. The next day and for the next month my lips and half of my face remained swollen. I couldn't eat or speak.
A week later I drank some ginger tea with honey, thinking it would help and well, it only made the inflammation worse and more painful.
I'll share with you what finally helped and what I think could've made everything better from the beginning.
1. Rinse with water. Water has to be lukewarm, never cold of freezing as it can compromise circulation. Just tilt your head and let the stream flow over the injury for several minutes.
2. Do not apply oils or any other substance. I used Vicco Turmeric Cream cream around the lips but never on the injury. The turmeric cream completely subsided the pain.
3. I didn't brush my teeth with toothpaste as it made it worse, I just rinsed with water or with water and a bit of salt, to prevent an infection. If your toothpaste is not strong, I'm sure it's better to use that. If you do use water with salt, rinse with plain water after a few minutes, otherwise it'll dry the skin of your lips.
4. After 2 weeks of little improvement and once the wounds were healed, I began placing my lips under the running water of the faucet. This time the water was as cold as possible. This reduced the inflammation greatly.
5. One month after the burn, seeing the inflammation didn't subside, I used an anti-inflammatory cream meant for muscle injuries, I applied an amount smaller than a pea along the sides of my face, almost next to the ears. This finally reduced the inflammation in about a week.
I hope this helps somebody.
