I'm kinda lost here man. So from what you said, it seems that you have started to take steroids for your lupus infection that you received from a doctor.
Then are you blaming people for saying it's OK to take Prednisone if you have a parasite infection?
If I recall, you started taking them for your lupus and you became infected with parasites and continued to take them.
Now are you pissed because others told you it's OK to take them while you have lupus and Prednisone?
This isn't a MD community but a source of info from what people know.
If anything, be grateful that you found out the truth on your own. That is the best way.
