Connie, I have found no solution to the armpit problem you described, other than workarounds like:

-hiding that area with clothes, or hair (Sapphire Fox hair, which is also beautiful, is easy to position over that whole shoulder mess while still looking natural.)  But hiding the mess isn't really practical for many poses, or nudes, so

-postwork smudges, cloning, etc.

You've probably already been something like this, so I apologize if this isn't helpful.

To help with the "other" shoulder problem (ie, the shoulder and arm bulge on the outside), I heartily recommend an inj/rem morph utitility by Maveris. There is an updated version at his site
Digitalmeanderings.com.  Look under Utilities.  I consider it indispensable.
