I have had a very mysterious and horrible skin conditions now for 2 and a half to 3 months. I have red blister like and very itchy pumps that are appearing from underneath my skin to the surface. I have one on my elbow that is blistering and full of pus. I have others that have yellow sap inside of them. I seem to have about 3 different kinds of rashes all at once. Also most of these rashes are worse at night. some of them come inthe evening and than disappear by morning. I have gone to doctors and so far no one has helped me with this condition at all and it is really troublesome. I dont want a bandade treatment. I need to find out the cause of this condition so it can be cured.
