Hi James,
I don't usually post on PN forum, but I saw your post and have a suggestion for you while you wait for any responses or information about the Diclofenac.

There is a search feature on the forums here and if you type in a keyword e.g. diclofenac or something else, you'll see other threads where this medication or issue has been discussed previously.
