Possible bib hanger injury

It was yesterday that it happened I had did 6 20min sets with 5lbs,didn’t notice it right away but now my penis has gained 3/8 girth and looks like a baseball bat. The only thing I can think of is I tightened the hanger to tight it was only uncomfortable at first no pain some discomfort taking hanger off to. I made this thread to ask if any one else has experienced this or wen it will go away it doesn’t hurt no discomfort either.

The swelling has went down a little. Still not sure of what I did.
