Hello and welcome to Mayo Clinic Connect, @martydav. You will notice that I moved your question to this existing discussion on shoulder replacement and pain. I did this so you can connect with other members like @colski @artscaping
@johnbishop and @mdgarnett who have similar experiences with pain after surgery. If you click the VIEW & REPLY button at the bottom of the email, you will be taken to the discussion and you can scroll through past posts.

How long has it been since your shoulder replacement and what is your pain at currently?
