What should the result be from injection?

I visited a urologist a couple years ago to consult about ED. They gave me an injection (not sure what it was) so they could check if it could give me an erection to rule out physical causes.

From my perspective it did not work, I could achieve an erection but it was no different than what I could do without the injection (around 50-60% hardness and went away very quickly). When the doctor came back to check on it, it basically went away instantly when he came in so he couldn't even examine the hardness other than his initial looking at it for a second. It did not feel like a normal healthy erection like what I used to have before ED. But because when he first came in it "looked" like it was hard, he told me that everything was fine and it was a normal erection, and that it just went away quickly because he came in...

I still feel weird about the whole situation so I wanted to ask about it, my expectation was that for a healthy penis using the injection would result in a strong erection that wouldn't disappear so quickly and easily, but am I mistaken and was just expecting too much? I still feel like there is something physically wrong causing my ED, but because the doctor determined the injection gave me a "normal" erection he ruled out the possibility of any physical causes and basically told me there is nothing he can do/no more tests they can do to determine the cause, other than giving me Cialis.

The erection strength on the exam room depends on the quantity of the compound you be injected with. Seems like you were dismissed. Have you considered having the exam again done by another Dr that specializes in sexual medicine?

You need to do several tests to try and rule out what could be causing your ED. And then, have a treatment plan in place.

Is it normal for it to be very painful? I know it will obviously be painful when the needle goes in but for me it was very painful even for a while after. I had to sit in a room for a while try to get it hard and it was really painful the whole time. I also am going through Peyronie's now and the area I can feel hard lumps is the same side as where the injection was, it's probably a coincidence but I wonder if it could have injured something...

I haven't really considered trying the test again but maybe I should eventually. I've been kind of demoralized about it, I've been to multiple different doctors and urologists over the last 7 years about it but they're all very dismissive. The first one I saw was supposed to be a specialist in ED and he didn't even do any tests beyond a blood test before telling me there was nothing he could do. He just prescribed me some medication I've never heard of or read about as an ED treatment and then when it didn't work he gave up. At least the most recent doctor seemed receptive at first and did some physical checks, but after the injection incident he seemed convinced everything was fine and became dismissive when I tried to tell him it was really not fine...
I'm also hesitant to try sticking a needle in again because of how painful it was and because I'm worried about aggravating Peyronie's which is already getting worse every week
