What Causes Swelling Of Penis When Lying Down?

Question: Dear. Dr. After fall injury, I have been having swollen penis/semi-erect when lying down, subsides when standing up or after walking for 10-15 minutes. Weird thing is when i sleep, i would get totally rigid corpus cavernosum and soft XXXXXXX & corpus spongiosum erection that would wake me up from sleep. I would have to wake up and walk around for these erections to go down. They would go semi-erect then it would take anywhere between 15-30 minutes for blood to drain. (as if vein drainage was blocked,,)

Went to urologist and did a doppler test for possible high flow priapism, however, it did not show anything (high flow priapism usually with high PSV) but my psv was 28cm/s and got a ischemic priapism from the doppler test which I had to get 2 injections to get rid of.

Urologist said everything was okay as per doppler, but my symptoms persisted and they decided to do an angio to take a look if there was something else going on. On the angiogram, on the proximal part (close to base/pubic) penis there was blush (not fistula) that extended all the way down to XXXXXXX of penis. Hence they embolized the suspected artery.

For the 1st time in months I did not get these painful night erection. by the 2nd day I got 20% chubby erection, then 3rd day back to these rigid night time erections. Now, I am waking up every 1 hour to prevent and drain the blood. I slept through couple times, woke up with severe pain & extreme coldness as if my blood circulation is cut off. My erectile function is deteroiating as well with these episodes,

Doctors are confused. Is there any possibiltiy that I might have high-flow priapism as well as veno-occlusive dysfunction? Any help would be appreciated
