No I was not on steroids but my friend in Spain was on massive doses of steroids for his asthmas before his infestation went beserk.
He ended up in a psych hospital for a year in order to keep himself from suiciding.
This gave him the chance to work on his treatments and he is cured now. He treated nonstop for six months.
I did not treat until a year after I was infested and by then they were all over me. Mites running across my face at night while i was watching TV. Sitting there with sticky patches to catch them.
