Hi, starting two days ago at night my body started to get itchy. But it only happens at night. I'm fine the next morning but it occurs again at night at that day. The next day, also at night, my body gets itchy and my upper lip swelling. At first I thought it'll be fine, but when I woke up it become worsen. Just like this image ->>> https://www.google.com/search?q=swollen+upper+lip&client=ms-android-samsung&source=android-browser&prmd=ivn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwipp4XX47PcAhXRb30KHaolCSEQ_AUICSgB#imgrc=a2hKh3b-SrocqM
Apart from that, I don't get anything like sneezing, sore throat, tight breath etc. Please help me, when will the swell goes down and what should I do? Thank you
PS - I don't know if I'm allergy to something because I ate Korean food before it occurs and I don't really know if I'm allergy to it because as far as I know I don't have any food that I allergic to
