Weird pressure in right temporal area.

Weird pressure in right temporal area when talking on phone — anyone else? Hey everyone, So for the past 3 weeks, I’ve been feeling this strange pressure in my right temporal area only when I’m talking on the phone on my right side. It’s not really pain — more like a dull pressure that sometimes lingers for a bit after I hang up. A few things to note: I don’t feel this pressure when I use my phone on the left side. No headaches otherwise, no ear pain, no vision problems. It goes away if I use speaker or earphones. It’s been consistent for 3 weeks now. I’m starting to get a bit worried. Could this be muscle tension from holding the phone awkwardly? Or maybe something with the ear or jaw? Has anyone experienced something similar
