I have the same problem! I've just been dx with MONO, age 59, so it's ridiculous... I have welts on my arm and face, and the bottoms of my feet and my mouth are burning (other than the other symptoms, of course... headache, malaise, fatigue,sore throat, swollen glands, etc.)
Anyone else here this old dx with MONO??? I think I already had it, too; both the old test and the new test (IGA/IGM?) were positive.
What does one do for immune dysfunction? Thanks.
What has your physician said about your hives ? I can only tell you that recently some people in this forum were discussing rashes that they had... this often happens in people with immune dysfunction.
How are they treating your mono ? And are you on treatment for your hives ??
