"Stung me on the bridge of my nose. One eye partly closed and the other completely. The fully closed one is just starting to open now.
Was stung on the head a couple days ago and hardly a bump. This one is so different."
By head i presume you mean scalp rab? not surprising - the skin covering the skull vault is closely attached to a thick layer of fascia overlying the bone with little in the way of soft tissue. Nowhere for the venom to diffuse to and nowhere for the swelling to form.
on the other hand, bridge of nose is loose tissue and adjacent to the very thin delicate loose skin of the eye lids. so a sting there allows bot easy diffusion of venom and likewise the resulting swelling.
the above is why blunt trauma to the head results in lacerations when it wouldn't elsewhere on body, why a neurosurgeon can "scalp" a patient to access the brain and why when a doctor/surgeon excises a skin lesion of any significant size from the scalp it requires a skin graft to make good (as the edges cannot be brought together to close) whereas a similar or larger excision elsewhere can fixed by primary closure with sutures, producing a linear scar.
