What is this?!? Parasite/mite? Please help

My boyfriend has been suffering from itching for almost a month now. It has gotten so bad that he scratches and picks his skin to sores.

He actually even started plucking at places in his skin where it was itching and he removed these weird bug like leg looking things. 😖

Not sure if its lice, mites or scabies? But its not getting any better on its own and I'm trying to convince him to go to doctor (he doesn't have insurance so he was hoping this would go away on its own but its not!) He is starting to cause some damage to his skin from scratching all the time.

Here are some pictures he took under a microscope. Any ideas? What are these? He says they're all over his body from the head down.

Thank you!

Leg or claw like appendage?

Also getting scared it may be morgellons. Please let me know what you think. Getting very concerned. ☹
