I pray for your family as you adjust and learn what's the new normal as healing continues. Hopefully the Dr team will find the right dose of meds for your husband's body to work with his new addition.
For the shoulder pain it really helped for me to get up and walk and some light massage. For me 3 1/2 weeks was when I began to feel much more human again. What really seemed to be the way I had the biggest improvement was when I got the okay to be in the pool. Just doing light exercise, stretching, and treading water seemed to lift the fog I was in and help relieve aches and give me a bit of energy. I still tire if I over do it but it's a huge welcome improvement. Your daughter will hopefully be noticing big changes soon.
