What is a stronger word for "sore?"

Thanks Bridget for giving a visual to how I feel:

I have started to work out again.

I guess being pregnant and having a baby are some pretty good reasons for talking myself out of going to the gym. 

However, now that my baby is 4 months old and I am still 30 lbs overweight I didn't have any more reasons not to go.

Now my body is saying "yeah, you think you can take an entire year off? I'll show you!"

And I respond with a whimpering "owie."
