Trimix, one side is not working!!!

[pdxboner]

Been using Trimix for a few years now. Last 2 times I injected on my right side it failed. One of those times I knew it was a bad injection, because it formed a small bump, which diminished quickly - I had a feeling that would fail. Second time I had a good injection, I thought, I aspirated - but had to slightly move need to get some blood. I did and injected - boner lasted a minute, then went away. I was using the 10 & 2 oclock angle. When I use the the left side, no problems.
-Is there scar tissue? How do yo feel for it?
-What methods do you use to ensure a good injection?

My corpora are not at the same level below the skin everywhere. Most of the time I can get into a corpus with 5/16in=8mm needle, but in two places I need 1/2in=13mm.

EasyTouch syringes have less friction than BD.

Several guys here, including myself use a VED to get a nice chubby.
Makes it much easier to locate corpora cavernosa.
Just make sure you're not too hard.

After about a year, I started having issues on one side and could clearly see an indentation over about an inch length. Thought for sure it was scaring, but when I had the implant, the sugeon reported no scaring. I still see the indentation, but it's bearly noticable now.
After I started plumping with the ved prior to injecting, it really helped. I still had to avoid the indent area.
