I am left handed person and using cell phones since last 20 years. I was also having habits to use earphones and listen music.
But, now since last one year I have earache and irritation with noise in my left ear.
I also went to ENT doctor but as per doctor there is no sign of any damage and looks ok.
But after taking some pain killer that doesn't affect anymore in my earache and I still have that problem.
Now, I also notice one thing in my ear that my left side ear has bit wide hole in compare my right ear. That I noticed while I tried to put my thumbs in my both ear and feel that my left side thumb going more deep in my ear in compare of right side ear.
That's weird but would love to know from some ENT specialists that exactly all these are cell phones effect or I have to count it normal.
