From the description it seems you might be having stasis eczema or varicose eczema over your lower legs. These are associated with varicose veins
and are usually seen in people who stand for prolonged periods
. These are characterised by dark pigmented skin, with itching, ulceration leg pain etc.
You need to meet a dermatologist
to get the diagnosis confirmed. As far as itchy eyes and running nose is concerned, it could be due to allergic rhinitis
and will respond well to antihistamines.
Hope that helped
