I had a c-section 3 months ago and since then i have been having sharp stomach pains from the top to the bottom, extremely gassy, starving feeling but nauseous at the same time, chills, and vomitting. Not to mention i have not gotten my menstrual back. My entire back hurts all the time and my left thigh feels numb at times. Is this common from such a surgery or could this be something else?
