Hi long time no read..
Sorry you are having more problems.

My shoulder is acting up so not typing a lot lately.
I did get some KT sports tape and watched some videos on how to apply for shoulder pain.
It seems to be stabilizing,supporting and helping with less pain.

So if anyone reading hasn't had a PT or chiro that tried taping, or tried the sport tape them selves, it might be something to look into.
Chiro had used it 2 yrs ago on my lower back and it worked well for that too.
She also did Graston technique on my low back but the taping gave extra support and stayed on for 7 days..
The KT sport tape I got from the store might be less durable as it loosens after shower.
