You need medical advice from a doctor, not anonymous opinions from strangers.
However...
A young man tells the doctor. "I have a rash on the end of my penis." He pulled it out and the doc hemmed a little and hawed a little before nodding wisely and saying, "You've got the clap."
The lad was horrified and said, "Couldn't it be something else, Doctor? Couldn't I just have a cold in it?"
The doc looked at it again, nodded wisely once more, and said, "It could be a cold, I suppose, but until it sneezes we'll treat it as the clap."
