Curiouser and curiouser.
The interesting thing about the spots on
@TiredSam's photo is that there is a slight pale halo around them. That indicates that they are not just tiny haemorrhages. They involve some sort of mediator release as in inflammation.
And I wonder if that nail fungus is really fungus
@Dechi? Could it be a nail dystrophy as seen in Reiter's or psoriasis?
The one thing that intrigues me is that various clues make me think of something called keratoderma or KB. KB marks are usually larger and slightly raised but occur on the palm and sole. They are due to T cells.
Edit: Sam did say his were slightly raised I see.
I think if there are actual vesicles, as
@strategist mentions, the problem is more likely to be a variant of eczema called pompholyx.
