Is this mastoiditis! Be painful right?

The left image is right side ear and the right side image is left side ear. My right mastoid bone is bigger than the left side. I had seen this many months back too. Coming to the problem, as i posted before. If you see, if i press beside the right ear's mastoid bone side, at a pinpoint location and palpate, then it feels sore. Otherwise if i put pressure on entire mastoid area nothing. I don't have clogged ears or earache. But yes, below ear, where the depression is there with neck, i get soreness there when i open my mouth. I had scope in my ear for checking few days back, there's no infection as mentioned by the ENT. Cbc is normal, hba1c as well But if it was mastoiditis if i put pressure, on the overall structure it should be painful right? But none is there.
