I'm sorry to hear about the earache you experience when talking on the phone. This discomfort could be due to several reasons:

• Pressure or Positioning: Holding the phone tightly against your ear might put pressure on the ear canal or surrounding tissues, causing pain. Using the loudspeaker avoids this pressure.
• Ear Infection or Inflammation: Sometimes, an underlying ear infection or inflammation can cause pain that worsens with direct contact or sound transmission through the phone.
• Temporomandibular Joint (TMJ) Issues: The joint near your ear can become irritated or inflamed, and holding the phone might aggravate this.
• Sound Intensity or Frequency: The way sound is transmitted through the phone receiver versus loudspeaker might affect ear sensitivity.

To better understand the cause and get appropriate treatment, I recommend consulting an ear, nose, and throat (ENT) specialist. They can examine your ear and provide targeted advice or treatment.

If the pain worsens, is accompanied by hearing loss, discharge, or fever, please seek medical attention promptly.To narrow down potential causes, we will need some more information.I understand that you are experiencing earache while talking on the phone.
