TMJ pain

I’ve got theeee worst sinus infection on the face of the earth after having a wicked cold for 2 weeks. 🙄 now it’s starting to get beyond my pain tolerance and my jaw is locked along with a splitting headache that will NOT go away with anything I can take. Urgent care was like oh it’s just a cold blah blah blah but I’m at a loss. Has anyone else suffered with TMJ pain and have anything that will help?! 😭😭😭
