The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
I would start doing some overhead carries, half TGU’s and arm bars. You can certainly continue to do soft tissue work that seems to be helping and opening ROM but if you don’t actually actively use the ROM consistently and focus hard on creating a good mind muscle connection after you have done some mobility work will leave you frustrated. These exercises are easily found on you tube. You could also do some ring rows and ring push ups and supports.
