Hi,
About a month ago I had pneumonia and with that I had a rash. That would appear in the form of hives at night. I went to the doctor and was given medication for the pneumonia and the hives stopped as well. Now at night while I am sleeping a red rash that also appeared at times with my hives is starting to appear on my knees. When I get up and have been up for about 30-40 minutes the rash disappears, then it will come back again the next night. I have not changed the foods I am eating, detergents, and change the sheets on my bed frequently, what could this be? If it continues I am going to go see my doctor. I also have psorasis, however this is not scaly, dry and bumpy like my psorasis. Any sugestions as to what this might be would be very helpful.
