I had abdominal swelling from something a while back. Clothes were tight for about a week. Around my waist where my underwear touched felt like it was sunburned, but there was no rash. The swelling has gone down but the burning feeling is still present on my left side. It is constant on my side, but spreads towards my stomach or my back on occasion and is just around my waist. The skin is sensitive to the touch but there is no sign of any rash or anything.
