porphyria

I have been electrically sensitive since 1998 when the building I
live in installed 9 more antennae. They already had installed 6
prior to 1998 which I did not notice any symptoms. It started off
with the tinnitus, headaches, digestive disorder and then I started
to get these huge blood blisters. I've been to a skin specialist
and he thought it might be porphyria but of course when I was tested
the results were negative. I still get the blood blisters and
notice that whenever the buzzing in my ears get worse then I get the
blisters. So far I only get them on my hands. Does anyone know
anything about this?
