I've been nauseous for three days. I can't eat anything because one bite makes me even more nauseous. My period ended two days ago, I drink plenty of water and fluids, I've spent time resting, I don't smoke or drink alcohol... I've also had very sensitive tender skin on my left thigh for three days, if I touch it lightly it hurts, feels like a bad bruise, but there is no discoloration and I did not injure it.
