Cortisone shot advice

I know that there are threads on here already about shoulder injury and Cortisone shots but I don't have time to look for them. I have decided to get a Cortisone shot this week for bicep tendonitis. My question is: Can I swim then? My fear is that if I do I might tear it and do further damage. However, I am also thinking that if the shot works, the inflammation will go down and I won't hurt it. Any advice and/or experience is appreciated. :agree:
