I have ED and a pain in my penis. Please help.

Hello doctor,

I am a 24 year old male, suffering from ED since the last one and a half years. I have gone through penile doppler thrice. The test which I took one year ago showed the PSV after 20 minutes as 38 cm/s, the EDV as 0 and the inner caversonal diameter was .15 mm and after the injection it was .70 mm. After the doctor had seen the reports, he advised me to take Tadalafil 10 mg and to masturbate after taking it. While masturbating, on the third day, I got pain in my penis, and it was in the middle of the shaft of the penis at the thumb point. I visited the doctor again, and he prescribed Polycovit, Mynubin-P, Zanocin 300, Trental 400 mg and I also masturbated four times a week. But still, the pain continued. So, I went through the test again eight months back.

The value of PSV was 25 cm/s and EDV was 0, but the inner caversonal diameter changed to .44 mm pre-injection and after. The third time I underwent the test again. The values were normal at 25 cm/s, and EDV at 0, and the inner diameter was .6 mm and after injection at 1.2 mm. I still have the pain in the penis at the same point. It has now been a year since the pain has started. There is no bending during erection, but there is a deformation in the penis like an hourglass shape and hard flaccid. Now, I masturbate only once a week. Is the 25 cm/s good or does it mean an arterial insufficiency? Does Peyronie's disease obstruct the blood flow in the penile doppler? I have no diabetes, no cholesterol, and I am not a smoker. I want to know why the flow is less.
