Hi everybody, a couple of days ago I woke up around 2am itching all over the place legs, chest, shoulders, arms, head, neck, crotch, and lips. My lips swelled up as well as my crotch area. The next day my thorat closed up and I had a hughe canker sore on my iner lip. I went to the dr and he ran blood test for food alergies as well std test including gentile and oral herpes test. All test came back negative the dr gave me a steriod shot for the swelling in my thorat and sent me on my way. My thorat is still sore just not as much as it was before and I still have a huge canker sore on my inner lip. This is the second time this has happen with in 6 months, and the drs have no answer for it. Can anybody help me?
