Extreme Bloating and Weight Gain Since Developing a Cold/Flu?

Hi, so I'm curious if any of you have had similar experiences with a cold/flu. 2 days ago I developed a severe cold (with the usual stuffy nose, sore throat, mild fever) and ever since then, everytime I eat or drink my stomach bloats out 2-3 inches, plus I've gained 2lbs in the last two days. My eating habits and daily activities haven't changed at all, so I'm wondering if having a cold, or taking cold medicine (I'm just taking Tylenol and Multisymptom Cough and Cold pills) can cause this kind of bloat/gain?
