As the nicotine is activated from the pouch you may feel a slight stinging sensation on the inside your lips or on your gums. This normally passes quickly. The degree of the stinging sensation can be accentuated by the flavours you are using.
Try switching sides in your mouth or drink a bit of water if you feel any discomfort from this stinging. If the feeling persists you may want to try a nicotine pouch with a lower nicotine content.
