How to resolve a mixed bowling action in cricket?

Un-mix it hahaha . I bowl pace and started getting injuries in my mid 20's due to my action so I slowed things down and changed my action so I was more side on. I bowled medium pace all season with this very side on action and it sunk in. The next season I went back to full pace and felt great and bowled more overs. Im not sure what type of action you have but slowing your pace down while changing your action is helpful.
