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.
