Viral pathogen causing pruritic papulovesicular lesions on hands

For the life of me I can;t remember the name of a viral pathogen a GP told me was causing a recurring pruritic papulovesicular rash on my hands (round circumference fingers, palms but not back o) of and soles of feet. After a few days the cluster of lesions plaque together then the lesions ulcerate.
I figured it might have been a Staph, Strep or Enterococci bacterial infection due to being at a muddy festival and getting my feet wet around the overflowing loos or recently replacing a particurly filthy bathroom and subsequently scratching my feet. Betnovate has worked in the past but it was likely only the corticosteroid component that was being used.

Doc said it wasn't and as it has occured last year and a few years ago he suggested first hand foot and mouth. As I've never had any facia lor oral  lesions he narrowed it down to a viral pathogen. Of course, I've forgot the name of it. It was two words.

It wasnt; my own GP I saw. The GP I saw is a sen clinical lecturer so I might run into him in the future in clinical years so embarrassed to ask him again.

Any suggestions?
