I'm exactly like you. Identical circumstances all the way down to the T. I've been suffering from what I believe is Morgellons for years now it's still afflicting me. Makes getting jobs difficult and life in general very difficult. I'm also blessed to have a place to live despite all this.
I also worked in shipping, items came from korea/china as well. I've pulled out red threads from lesions and what looked like small clumps of white hair all tangled up. I'll pray for you, anon. I understand what you're going through.
Anon, do you ever see anything like stretchy white plugs in your wounds?
I will research the remedy you have offered, thank you.
