Do you really mean this? :eek:
A “normal” case of the flu leaves you literally bedridden for a least a week. And I mean literally. Standing or even sitting upright for more than 15 minute is almost impossible. Sleeping 16 hours a day is normal. And that’s a mild case of the flu. A bad case of the flu means that you can’t stand unassisted, and you *will * be hospitalised.
A lot of people think that a bad cold is influenza. It ain’t. If you’ve ever had influenza you know the difference.
Assuming you are mistaken then you just had a bad cold a month ago, then everything else is almost certainly related. The infection will have weakened the affected tissues and left you susceptible to further infection.
