Jaw pain!!

so I'm 19w2d and my jaw is in so much pain and this happened randomly in the middle of the day yesterday and it wasnt bad pain ether now it's gotten to the point where I don't even wanna open my mouth. it hurts when I open it and it's like dull annoying pain when it's closed but still painful. I had my wisdom teeth removed long time ago and it's on my left side. I honestly don't know how to get rid of this pain I've tried everything and the pain only goes away for 5 secs and then comes back more painful. I don't have a doctor where I live and my city doesn't have a walk in clinic.
