Hi, I have the same problem as the brown discharge from under a bruised toenail, but I also have what I think is Psorrias on my palm of my left hand, the one that blisters under the skin then goes dry and peels. I have had 2 courses of heavy antibiotics and cortisone creams etc and this has been going on for about 9 months now, I was wondering if all this is related I think the Psorrias started from a small blister when I broke my wrist and the cast was put on too tight they treated it as it was staaf and it has just never healed, just spread. I eat really healthy, I am average weight , I am not sure what I should do next, thanks Sheryl
