For about 3 wks now Ive developed a rash,or hives on my face only.Its calms down,and lately when I eat ,the hives come out.It started out with a rash bout 2yrs ago .I noticed when I started losing unintensional weight.It went away for a very long time,but now I have it with hives.Its embrassing everyday I go to work.I been to a kidney dr.,cause I have kidney problems,and he just said,'oh its nothing'.I'm sick ,and tired of dr's saying theres nothing wrong.What kind of dr should I see for this.I cant wash my face.or put any creams.and I have a red bumo on my nose that doesnt go away,and its not acne.Please help........................
