What could this be?

[Universe11]

I have had this in my upper arm. Noticed it last night, was a little itchy but haven’t noticed all day. Looked and it has tiny little blisters within the rash. Not itchy at present. Any ideas?

Looks quite like shingles? Any pain there at all even before this came up?

No nothing at all. It’s not itchy either. X

I am actually getting pain come to think of it, like a stabbing pain down my arm. Is that normal?

I had shingles on my back and it did feel like shooting/stabbing pains that made me flinch.

Looks like shingles to me. You don’t always get pain when they start.

Shingles or cold sores (you can get them anywhere). They often start off looking very similar.

Agree it looks like shingles. Can you go to urgent care centre or similar today and get some anti viral tablets?
