for the past couple of weeks i have had a severe heat rash all over my neck and inner forearms and have been avoiding sun and heat and washed with coal tar soap and applied aloe vera  gel . today I feel a chill with a slight pain like a fever on the surface of my inner arms .I wonder if that could  indicate an infection
Hi, Feeling of cold and pain may not be due to infection, but it can be due to nonspecific reason it can be temporary.  Sometimes allergic condition may cause such symptoms, it is nothing to take with the soap or gel no need to panic or think about infection for sure it is not an infection, nor it is the disease condition. Hope I have answered your query. Let me know if I can assist you further.  Chat Doctor.
