My poison ivy appeared in patches, not evenly all over my body. This
may not be poison ivy. A lot of the bumps have been scratched and
could become infected, so something is needed to remove the itching.
If it is poison ivy you may need a hormone shot. You can tell a
bedbug infestation by their feces they leave behind. Skin breakouts
can be difficult to diagnose and may be a symptom of something more
serious--see the best dermatologist you can find.
