Injection failed caused curved semi

[DP5689]

Hi guys.

I just had an injection for the first time to do a doppler ultrasound. I expected the injection would give me a hard erection but it didn't. It just caused one side of my penis to swell up and made it curve (I have never had my penis curve like that before).

Is that common to see? The doctor only used a small amount, he said he didn't want to risk causing priapism.

When you guys inject do you do it fully flaccid or do you try to get some blood flowing first?
I was turtled (shrinkage) when they administered the injection.

Are there any risks from a single injection?

Thanks

Could that mean I have venous leak on the left side since the left side didn't fill up? My erections aren't normally like this. I'm just curious since a lot of you have used injections if you've experienced anything like this. I'm not sure what to make of it.
