In brief: Can't

There's an old saying in dermatology: you can't diagnosis a rash over the phone.
I even get confused after seeing some rashes. Generally, allergic rashes are welts but some allergic rashes are small red dots. Best to see your dermatologist.

In brief: Rash

You really need to have a doctor look at it to determine the difference.
Allergic rashes tend to be short-lived and might be a simple hive appearance to it.
