Yes, I have had this with mercury. Sulfur would bring it on worse, so it sounds like you might be experiencing this. Often changes in temperature would be enough to stir it up as well and even my ears would itch, go hot and red. Could happen after taking selenium, eating sulfur foods, going from a heated room to outside in the cooler air.

I no longer get this, but did when I had a lot of mercury in me. But more than that, I used to get rashes over my entire body from mercury trying to escape via the skin. Itching, burning, tingling, the whole deal. This happened after amalgam removal because I still had a lot of stored mercury and I believe my body was making an attempt to eliminate it.

I also used to get burning on the soles of my feet when I had amalgams. and some itching when I would have a bath. I also had strange symptoms when I would drink hot fluids, which increased the uptake of vapor from my fillings. Giggling, hyper, wheezing in the lungs, etc.

Got the same when taking a bath.....so mercury can do some very strange stuff when it gets stirred up or "heated". It takes heat to make mercury rise, which made all the sense as to why it would rise up onto the skin if I would heat up.

It's usually known as the mercury rash. Mine mostly occured after I was given a DMPS IV injection, which basically just pushed a huge load of stored mercury everywhere and from then on caused the most unbelieveable extensive rashes, that occured upon bathing or exercising or taking anything to stimulate metal chelation. I would be covered literally from head to feet, face, ears, hands, feet, etc etc. Had to be seen to be believed. I would often be so deformed from this, I had to wait till it settled before I could go outside. Sometimes more of the rash would come up later though, so I never knew which way things would go. It was like heating up from bath would bring it up, cooling down would stimulate it further, and I would have to wait until everything became settled and even again.

It is a very volatile and weird metal.
