This always happens to me and I'm hoping I'm not alone. Does anyone else have this problem?

The day you feel a little better from your flu, but still are very tired but can actually communicate (hehe)passes, and the next day, you feel completely better except for still being a little tired, and for this. The virus for some reason spreads down into your calves and causes your legs to hurt every time you try to walk. It doesn't feel like a sore or aching feeling, it's more of a sharp pain. I ALWAYS get it right when I'm over the flu and it lasts for 3 days usually. It's very annoying as it makes me have to crawl around the house. I have to stay home from school all because I can't walk.

Does anyone else have this problem, or could they explain why it happens?
