Fluid retention? Glandular Fever?

I've been retaining water in my stomach, face, arms and legs lately. I've been flu-ish and lethargic but I thought that was nothing to worry about. I mentioned it all to my doctor and he said it was likely a food intolerance or IBS, both of which we eliminated. Recently I went to the ER for an unrelated matter and the doctor told me my lymph nodes in my neck and armpits are very swollen and I likely have Glandular Fever. My question is, would this account for my water retention or is it something else? My weight's been varying 10-15lb in a matter of days, it's very frustrating.

Hi, that large amount of rapid water retention seems very unusual. But I wouldn't think it's lymphoma related at all, and also I don't know why Epstein Barr could account for that either - unless the virus has affected your kidneys on some unusual way.
