Hi,Ive had a cough for a while now and I thought that was it until one morning I woke up and had some sort if rash on my knees and by my elbows and thought it was heat rash because it went away. I just got the rash on my knees again and Ive noticed that my palms and feet get itchy before the rash shows up. Any idea what it could be? I havent been to the doctor yet but I have taken Benadryl and it has been working
Hello, I can understand your concern for sudden occurrence of rash on knees and elbows and rest of body. After reading your it appears that you are suffering from \"Urticaria\". Urticaria is a common condition caused by bursting of allergy producing cells known as \"mast cells\" due to certain aggravating factors present in the environment. As the chemical inside them is released it produces a rash which you have mentioned. There can be multiple factors producing this condition which are included in day to day life and sometimes it is really difficult to find one exact cause. In your case you are correlating it with exercises, hot climate, spicy food. So it is better to stay away from the offending factors. The long term effective treatment for this is by oral anti histamine like loratadine under medical advice. It is one of the Chat Doctor.  Do not scratch or rub the skin as it can lead to further aggravation. Take care.
