Jaw pain

I give my man blow jobs.. like a lot. I like it a lot but the past few month my jaw had been getting tired like 20 minutes into it. (Sometimes we play for like 1, 2, or 3 hours) anyway, the past few days I have been having a stabbing jaw pain. It came out of nowhere while I was sitting down watching TV. It lingered for the rest of the night and bothers me sometimes when yawning or sticking my tongue out (like to lick ice cream). It’s not as bad as that first random day but today our of nowhere it was just painful for a few seconds. Anyone else experience jaw pain? What do you do about it? Because I really want to blow my man again but I’m afraid it will hurt me more.
