My fiancee & I train together,and one of the biggest adversities in her training has been chronic trapezius pain in just one of the traps. Just yesterday, she had to completely stop working out just after the first exercise(sumo deadlifts…).
We have had to do so much trial and error to see what exercise do and do not work for her,so that she can still have a comprehensive workout,without having debilitating trap pain that follows her for days,gives her bad headaches,neckaches,makes her depressed,etc…
Does anybody know how she can do Side Laterals/Rear Laterals/Possibly even front Laterals(not necessary) or any other exercise that slams the side+rear delts hard while using miniminal traps?
Perhaps there is just some variation of them,whether it be free weights or machine to not aggravate them?
So far these have been the only exercises for shoulders that have not hurt her:
1- Incline Bench Press, paused high on chest [No pain! works great]
2- Face Pulls [Seems to be working well,no pain & hits side/rear delts]
Ones that are hit or miss(may or may not cause her pain)
1- Reverse Pec Dec Flyes
2- Side Lateral Raise with dumbbells (but 70% of the time she does get pain)
We really need more rear/side delt exercises(maybe even 1 more front delt) for her,or variations,or ways of execution to use MINIMAL TRAPS and not cause all this terrible pain and stuff 
Help is appreciated.
