Hi, have you seen a Dermatologist?? It sounds like you may have psoriasis, which I also have. There a many differnt types of Psoriasis and you can have more than one type. Here is a link to a forum on the National Psoriasis Foundation that has some good info. There is a Complementary and Alternative section for people who want to try natural things to try and control it. http://www.psoriasis.org/forum/forumdisplay.php?f=21
If you go to the main page http://www.psoriasis.org/home/
There is a section that shows pictures of the different kinds. You could try and see if anything there looks like what you have. Besides the plaque type there is a type of Psoriasis that is kind of like a pimple and could have clear liquide or puss in it when they are broken open.
