If this skin change is over your entire body you could have Addison's Disease. It causes severe leg pain, weight loss, and electrolyte imbalances detected by blood tests. The skin change would have to be everywhere including areas which are not exposed to the light. If this fits you, you need to see a doctor right away.

I thought necrosis too, but hard to say. Possibly a clot maybe? But I don't know if that is something that would come and go...

Agree, not much info to go on. In addition to above, how long has it been this way?

Darkened skin would make me think of anything from bruise to necrosis. If it's definitely not a bruise, then a doctor should see it. If it is the cause of the person's pain and weight loss, I would not wait as the infection could spread thru the body. If the person has a fever, I would consider this an ER situation.

Does it fit any online descriptions of a spider bite?

There isnt really enough information to go on.  First, where is it, How much of the area is black?
What does it feel like does it itself hurt, does it feel numb tingly?
