I was scheduled for a TKR but insisted I have blood test for allergies. This blood test determined I was allergic to 5 or 6 metals and like you aluminum was high, nickle moderate and the others mild. My ortho was shocked, he said aluminum allergy was rare. Like you don't and never have cooked with aluminum. I don't drink sodas.
I sure hope you try the cilantro detox. I worked for me. It is a heavy metal detox and I also still take the chlorella tablets.
Frogger is another "old geezer", who doesn't blog so much anymore as he is still in remission I believe. He also had great success with cilantro. He is stopped using after he went into remission and although it put me in remission after a few months I was on it for about 10 months and went off in October because I started getting skin darkening on my cheeks. Over consumption of cilantro causes this. Still no new breakout. This is the longest I have ever been in remission.
Pressure caused severe pain for me, on top of the itching. I couldn't lay on my back or lean back in a chair or car seat. I know my skin is permanently changed as I always have a few bumps and scabs on lower spine area, but they are not itchy.
Stay hopeful, although my first outbreak lasted a full year, a year of misery, now 4 years later feel fantastic. One year is not unusual for a first outbreak. I am realistic and know it be back someday.
