Exposure to cold air can irritate the nerves in your face and ear, or trigger muscle spasms, causing pain and temporary difficulty speaking. For immediate relief from the discomfort, you can take over-the-counter pain relievers like ibuprofen or paracetamol. Applying a warm compress to your ear and jaw can also help soothe the area. However, because you are experiencing difficulty speaking, it is important to be evaluated by a doctor or an ENT specialist. They can check for conditions like temporary facial nerve irritation and prescribe specific medications if needed. In the meantime, try to protect your face and ears from direct cold drafts using a scarf.
