A red rash then appears on my hands, usually between my thumb and forefinger, in March April. This
rash eventually spreads to my forearms and lower
legs (though it is never as visible on my legs - I just know it's there by the itchiness). The rash on my forearms gets more pronounced (itchier and redder) with the heat and sun. I'm not sure which is aggravating it. Also, the pigmentation on my arm eventually becomes patchy.
