I agree wit what is posted here. I however got the flu and yeah it kicked me down BIG time.
I have SLE and also MS but WOW...
I will spare the details as I do not want to scare anyone. The good news is I am about 60% better and now truly know in my heart that I will recover from this flu.
When in doubt talk to your docs and boards such as this one and the lupus one are huge help esp for support.
Wishing you health,
