A fluid filled rash all over the body after exposure to a metal is usually allergic contact dermatitis. allergic contact dermatitis can happen not only in the area of contact, but all over the body, which means that the allergic process is very severe. We have to do a patch test where a small quantity of the metal is applied on the back 48 hours on the skin and this is a simple out patient test and it will prove what are the metals that you have to avoid. There will be a list of metals, the use of which you will have to avoid. You have to also investigate if the rash was unrelated to the contact of the metal. So meet a dermatologist at the earliest for an expert opinion.
