joyce are you and steve on any sort of nutritional or supplement regimen? all those infections are making me think ACESZ for both of you
(vit A, vit C, vit E, Se, and Zn)
the zinc might help with the ED too. it boosts testosterone and zinc is on average low in ms patients too.
try google searching zinc erectile dysfunction
and have a glance over the list of results.
just let me know if you want any info on nutrient sources, preferred supplement forms, dosing, optimal levels, etc.
