My husband just had reverse shoulder replacement surgery, his was under general anesthesia due to complicated case and stayed overnight to watch for infections. Yes it’s not uncommon to experience anxiety issues over surgeries. He was anxious before surgery and is better now but he worries about being off work onFMLA for so long etc It’s a typical reaction to invasive surgeries: worries, depression, anxiety...
I am surprised you have bad experience with doctors, or do you think they might treat you bad? We only had great experiences with hospital staff and his surgeon is great. I think it might depend where you live? Hospitals are great by us
Having said that, if you experience swelling you call a doctor. They are more likely to be irritated if you don’t call than if you do. In addition hospital paperwork indicates when to contact them. What does your say? What about swelling? Please call them. When is your first post op appointment?
