Blisters (finger): There are almost limitless causes of blisters on the finger. Course contact dermatitis is the most obvious cause especially if you have any rash anywhere else, but there are such strange things is herpes zoster appearing first i'm just a single finger, which we've seen many times. What's the real answer this go see your dermatologist because she/he needs to lay an eyeball on the lesions to tell.
