How Can I Stop This Unbearable Itching?
It is in both my arms and happens mostly at night and prevents me from sleeping. I have tried anti-itch creams, home remedies, allergy medicines, etc. I think it might be nerve or stress related but don’t know what to do about it.

…sounds suspicious for scabies, which notoriously causes awful itching that is worse at night, and can even keep you from being able to sleep.
I’d see a doctor and discuss. Treatment usually involved covering yourself in a cream from your neck to your toes for about 12 hours…and repeating a week later (sometimes).
Otherwise, it could (rarely) be an indication of a liver problem…
And make sure you don’t have “bed bugs”…which are making a “come back” recently…!

I hope this helps!
