Friction induced urticaria, perhaps from the seafood you had the night before
If the lesions are found both on the hands and feet, then dyshidrosis,
pustular psoriasis, and hand foot and mouth disease should be considered.
Regarding #5, what kind of seafood would one have for dinner that would cause "friction induced urticaria" of the hands and feet? Would have be some rough and resistant bivalves and crustaceans ; )
Regarding HFMD, the following describes (and contains photos of) of the condition -->
Hand-foot-and-mouth disease - MayoClinic.com. According to this definition and symptom description, the OP would seem to be a monosymptomatic case. As such, I find this a reach as a reasonable r/o dx.
Finally, leaving aside the rarity of pustular psoriasis (NOS), I don't find this compelling. Neither the description of the lesions nor the history appear consistent with palmoplantar pustulosis.
