I got my girlfriend's mood ring stuck on my penis, do I need to go to the hospital or can I remove it myself?

My girlfriend and I were showering together and don't ask how but the subject arose of how my softie looked just like someone's finger, so I grabbed her mood ring off the counter and decided to slip my penis through it, and it was fine while it was soft but then it got hard and now the ring has locked all the blood in it and I can't get soft again. Can I take care of this myself, because I really don't want to go the doctor and explain this and have people looking at my modestly sized manhood?
