Oi've got blistahs on my fingahs! :whistling:
I'm sorry to say I have nothing much helpful to add I've taken both of those drugs, but coming off neither of them caused me blisters. You've probably done this already, but have you considered what else might be causing the blisters? For me, causes have been playing guitar when out of practice, and sometimes warts--which might be mistaken for blisters. Also, if you use a bleach solution in which to wash dishes, as I do, you might experience some blistering on the fingertips through contact with the chlorine.
