first sorry for my bad English.
One week ago ,I was Masturbating, I felt pain in left side of my penis and the left side got painful and red.
After it finished i felt pain on the left side and for next day I didn't touch it,till it got really better.
when i again did it it got painful again but this time worse.
Now ,I have pain on left side (just behind the head and when i move it usually or make foreskin back .
I felt pain there .
MY questions are these;
Will it heal like first day or it will become like with a touch get painful?
Does it self heal or i need any kind of check?
(right now its not red and pain get less but pain not fully go)
