I must be lucky...I have a White's Fusion Bullet that I dive and never get hickies from it. In the summer I dive it with cold Under Armor gear and keep enough gas in there to relive the sqeeze and still never get hickies.
 
Not enough air in the suit (underweighted) and/or no drysuit underwear.

This has been the cause of several suit hickies here in HI, where I'm using a fusion bullet with no undergarment or just a lavacore shirt to stay warm on extended hangs. Oddly, it hasn't felt restrictive, too tight, or at all painful on the bottom when this has occured. Fixing it was just a matter of closing the exhaust valve a few clicks more and running a bit more bubble in the suit/a bit less bubble in the wing.

I wonder if having a nice slippery layer like UA helps there? Makes it hard for the folds of the suit to pinch skin.

That could be true but like I said, I always keep the squeeze off by putting gas in my suit. I have come up at the end of a dive feeling like I was wrapped in plastic wrap...LOL!!!

I've been diving dry suits for about 4 years without any hickeys - but finally had something similar happen. It was during a cavern / cave dive - with the cavern passage sloping about 45 degrees downward. At a depth of about 80 feet - I wrestled with a restriction - trying to get past the flow. The majority of the dive was spent with me in a heads down trim - a little greater than 45 degrees.

At the end of the dive - I had the following over my shoulders and upper arms. It never hurt - but I was more focused on the restriction than anything else.

:shakehead:

I think the extended vertical (heads down) position is what really does it. When most of my dive is horizontal - there are no issues.
