Right retromolar region pain
Suddenly from past two days I am having pain in the right retromolar region while eating, swallowing or moving jaw. I can't open my mouth much because it starts paining. I can't see any visible symptoms inside mouth..just slightly red. There is also burning when I eat spicy food. When I touch the area I can feel a slight swelling or lump which is paining when pressed. My upper right wisdom tooth is impacted which pushes against the cheek and back, but not sure if that is the culprit. The pain and jaw stiffness is worse in morning. Feels like there is a cut or canker sore hidden there but I can't see any. I've taken 2 zerodols which is helping a little with pain but not curing the problem. I can't visit a dentist for another two weeks as I'm traveling in a place with no good medical facilities. Any advice for the time would be very helpful.
