Hello Nutty, Hydromophone is not an anti-inflammatory.
Here's what this articles says.

Heart function and circulation can be affected in patients with SLE.

   * Pericarditis (common)
         o Chest pain occurs and can be intermittent. This pain is often
mild, but it can be severe. The chest pain can be sharp and retrosternal.
         o Diagnosis of pericarditis is through the presence of a
pericardial rub, electrocardiogram (ECG), and echocardiogram (ECHO).
         o Pericarditis is treated with NSAIDs and prednisone.

   * Myocarditis (less common)
         o Shortness of breath may be reported on exertion and while the
patient is lying supine.
        o Orthopnea is noted and is aggravated when the patient is lying
flat.
         o Cardiac arrhythmias may be present.
         o Peripheral edema also may be associated with myocarditis.
         o Diagnosis is with increased cardiac CK, ECG, and ECHO studies.

         o Treatment of myocarditis is with steroids.

Here's a list of NSAID's
ibuprofen (Advil®, Medipren®, Motrin®, Nuprin®, Rufen®), indomethacin
(Indocin®), and naproxen (Aleve®, Anaprox®, Naprosyn®).
Valdecoxib/Bextra, Mobic/ Meloxicam  , tromethamine (Toradol
There's many more anti-inflammatories.
I was thinking if you combined one with food and the steroid....
However, I really feel that a heart specialist and pain specialist and
rheumatologist should put their heads together and decide on a treatment
plan for you (and continue to monitor you).
