 [ Symptoms ] i have a itchy rash that comes and goes what could be causing this  the rash appears in different areas of my body for an example a rash showed up on my wrist and stayed a while and went away later the same day it appeared on my stomach and then on my thighs etc its itchy while it is present at one point my hands first turned red and then start to itch really bad to the point i had to wash my hands repeatedly i work in the medical field so i wash my hands a million times a day what could be causing this reaction [ Disease ] i have had the same for 1 month and think i figured mine out msg i have never been allergic to anything and have had many ramen noodles over the years perhaps i have developed an allergy i suspected ramen and when i did not have a reaction the past couple days and no ramen i was thinking about trying them again to see what happened i did not try them again but tonight i had a reaction stumped i checked the ingredients in the chips i had an hour before and sure enough they contain msg
