If you did indeed go for a run, you would have discovered muscles you never suspected existed. If, twenty four hours after your first run, you are able to walk without wincing in pain, you are either Super(wo)man, or lying about not being a Runner.
If you are rudely woken up from a deep slumber, wouldn't you be grouchy? That's what you have done to your running muscles. The pain is necessary part of getting them working. Embrace the pain.
Work those muscles again however lightly. If you don't, you'll only have to go through the pain all over again.
