Pain/tenderness/soreness in this area.

So, i had cough since 2 months and i had ceftum 500 before for 5 days in the 2nd week of feb but sore throt was there and wasn't going away. So, on28th feb i showed it to ENT, he prescribed Cepodem xp 325 for 10 days and ab phylline for 10 days as well. So far m doing better. But sonce few days i have pain/tenderness in the area shown in the image. 2 years back i had a wisdom tooth extraction. After a month of that, when i clicked my ears to open up, that time this time of soreness happened. And some variant of zerodol was given to me and it resolved. Same kind of pain is happening again, I remember i tried clicking my ear area recently weeks back. Why is it happening? As i am already on antibiotics, I don't think this is an infection? Please help me. Do I need to take anti inflammatory as well? If yes, please suggest. Thank you. All bloodwork came fine. And yes, if i press that depression area and open my mouth, when my finger is rubbed with bone, it hurts.
