Yes, it felt like someone was pulling on my insides. Also, I would have pain if I sat for awhile or walked to much. 2 weeks ago my family and i went on vacation to San Fransico. I walked so much and was very sore in the evening but it was the best thing i could have done. I feel back to my energized self minus the over eating.lol It gets so much better...I fell 100% better.
