I am 57 yrs old and was diagnosed with MS in 2001.  I'm inject Avonex weekly.

Beginning about two years agp.  I began having symptoms of a Urinary Tract Infection every few months, primarily pain with urination and urinary incontinence that went away after beginning antibiotic treatments.  Needless to say, I had little or no warning when I had to urinate, and yes I managed to wet my pants more than a few times before deciding to use pads or disposable underwear. 

A few weeks ago, I developed what turned out to be a yeast infection in my armpit.  I also developed urinary incontinece, but once my yeast infection was treated, the incontinence subsided.

Once again I developed symptoms of another UTI and am taking antibiotics (Ceftin) and my urologist had my recent urinalysis sent for a culture.  The results showed a minor UTI.  My temperature is normal and my incontinence is once again going away. 

I'm now wondering if whenever I develop any kind of illness, infection, or virus  I can expect to have an MS flare up or exacerbation in the form of incontinence.  I also read the warning signs associated with Avonex, and noticed incontinence as a possible side effect.  I'd appreciate guidance or advice from anyone concerning my situation.  Thanks in advance.  Suzy
