small brownish patches on skin of leg?

[Guest guest]

Any idea why a possibly mercury toxic person could have small brownish

black patches on the skin of the leg? This is regarding dh, who did

meet the counting rules, but we have not done a Porphyrins test yet to

figure out if other metals are involved.

He has these patches on one leg below the knee area. We noticed it

after a recent problem with itchy skin that he had in various areas of

the arms and legs, chest and back. (I applied coconut oil, started

supplements of Lysine, B-Complex, Vit C, folic acid, which is keeping

it under control - I do suspect that when he indulges in his sweet

tooth the problem gets exacerbated).

The interesting thing is, his dad has the patches to a larger extent,

had premature greying (as dh), happened to work in the metallurgy

department (no idea if there was exposure), and now we are wondering

if his dad has mercury issues too.

Are the patches totally unrelated?

Thanks
