Melissa,
Sorry that it has taken me this long to respond. Apparently I''m easily confused these days and sent a PM to someone else, thinking it was you

.
They have responded and now it is all sorted out.
I too have been diagnosed with Parvo; and have been dealing with the joint symptoms for the past 4 months. The docs are looking into using IVIG as a therapy to help the body get over the virus.
Have you had any therapy suggestions?
I posted a thread on the MS forum (was diagnosed over 30 years ago and have SPMS).
