I have an enlarged, tender xiphoid process. It is only painful and bothersome after I have gently touched it to see if it s still there. I have not had any known trauma to that area. I am a 43 year old male, 6 1 , 230lbs. My only other medical issues are high blood pressure, which has been easily controlled with medication for the last 10 years. I do take a 20mg cialis once a week. Any ideas on what caused this, what is means, and how serious is this?
