Say no to reverse shoulder replacement

Is anyone else regreting their decision to have a reverse total shoulder replacement?
I am about 9 months post surgery. The pain in my right shoulder has not been relieved. In fact it's much worse than prior to my surgery. I'm also very weak in my right shoulder. The doctor has sent me to PT ever since my surgery. According to my physical therapist , I have a severe deficit in the mobility and strength for my right arm. I have exercised my arm almost every day since my surgery. Does this get any better? It's definitely changed my way of life, driving and cleaning up my house is painful. I vacuumed my house, and I was sore for three days. I hope there are some insights on how to proceed with my recovery.
