Poor Joey - that has got to be uncomfortable. My RB kitty August once stepped on a staple; the vet removed it from his toe and had me soak his paw in warm water with epsom salts 2 -3 times a day for a few minutes to clean and sooth the wound; also to help with any potential infection. The epsom salts were not popular with my boy however he did tolerate the soakings and his paw was better within days.

Morning can't come soon enough I'm sure ... hope Joey gets feeling better soon.
