Below mandible achy/throbbing pain. Do?

So here see in the picture, i have a throbbing pain when i massage that place or move the muscle with my finger at that place,i get no issue when doing normal activity. The area which is marked as red line, there only i get the pain. I got it checked by an ent recently he game my amoxyclav + zerodol mr. Since 4 weeks back i had a wisdom tooth extraction, but i had taken antibiotics then too. Coming back to now i checked it with my dentist he checked fr any infection but it was nt there, but after eating the meds for 3 days too, the pain remains like that... what shld i do? And note the pain only can be felt when i click my ears or massage that area, its feels like a sharp throbbing pain, doesnt occur when i move my jaw left and right.
