I haven't been exercising regularly, so now that school is out, I've decided to try and walk 30minutes a day like my nutritionist originally recommended.

Yesterday I walked a brisk 1.5 miles on the track (took me about 20 minutes) then in the evening, I walked a slow, leisurely 3/4 of a mile with my husband(that took about 15 minutes).

The strange thing is not only my legs are sore, but the sides of my torso are sore (about from my belly button to the top of my waist). When i cough, the muscles there actually hurt (kinda like when you catch a cold and you've coughed so much that your ribs are sore). My thighs are also sore, but that's to be expected I guess.

Had anyone else experienced this? When i did a combination of walk/running on the treadmill a few weeks ago, I wasn't sore in my lower waist afterward. What gives?

I don't have an answer to your question but congratuations on the walking

I don't have this. I did try to up the walking to jogging yesterday and I literally felt a staple move or something weird in the stomach area towards the back. Sticking with the long walks for now. I am fine on the elliptical. I love and hate that thing, it kicks my butt but I know it works.
