irritation at tip of penis

The opening at the tip of my penis seems to be irritated.  There is no discharge and it does not burn when I go to the restroom.  It does seems to be a little puffy and at times a little red.  It seems to be the worst when I work out, by the way I wear loose boxers.  I went to a dermatologist about two weeks ago he said that He didn't see anything to worry about.  Is there anything that I can do to make this feel better?  medicine different underwear.

Ray:

Irritation at the tip of the penis almost never means anything infectious or serious, and the fact that a dermatologist looked and saw nothing is even better.  My advice: apply 1% hydrocortisone (OTC) twice a day for a week.  Drink 3 gallses of water, juice, or milk per day.  Then forget about it.

Best.
