Actually this morning when i woke up and want to go to pee, i felt that my penis (behind the foreskin) swallowed  and I got worried, did not know what happened to my penis, (it is somehow aching and half of it swallowed , but want to tell, (I had a cough and coughing press had a kind of press on the left down my belly,) i ask if it is the cause of the swelling.
