Hi all. My son is 2 and has inherited C4 deficiency. He has been doing very well except for red and swollen feet at times. Today he woke up with a few hives. They went away and then They came back about 3 hours later. They are in clusters of 5-20 and look like little burns. They will go away and then reappear in another part of his body. He has had them on all parts of his body. I gave him benedryl at lunch time and they went away for about 2 hours and now they are back. Could this be the start of something that I have to watch out for? I have not delt with an immune disorder before and don't know what to look for. I have gone over it many times in my head I can't think of anything that he may have eaten or come in contact with in the last 2 days. Anyone with any input would be appriciated.

Thanks
Wendy :confused:
