Hello,
Yes, you can use a topical anti-inflammatory such as antiphlogistin or voltaren following a cortisone infiltration.
In fact, cortisone can take several weeks to take effect. It is perfectly safe to use another pain reliever while waiting for the cortisone to take effect.
Be sure to follow the instructions for using these products and avoid applying heat following the application of these creams, as this will increase their systemic absorption and thus increase the risk of an adverse effect.
Also, given your medical conditions and the medications you are taking, voltaren or other similar cream is safer than naproxen taken by mouth. Naproxen interacts with many of your medications that can cause increased blood pressure as well as acute renal failure. Because of its low systemic absorption, voltaren is a much better choice.
Finally, unless your doctor advises otherwise, don't hesitate to use acetaminophen as well. It is a non-anti-inflammatory pain reliever that can be combined with voltaren (or antiphlogistin) and provide additional and complementary relief.
Do not hesitate to contact me with any additional questions.
Looking forward to it!
