What Causes Nausea And Pain In Left Leg?

Hi Feel really nauseous everyday for the past week or so edlecially in the morning but it usually passes after a while however, today I felt like I was going to vomit after eatinga kiwi at lunch time. I have recently switched my contraceptive pill. I wason ya but am now taking yasmine for the past two and a half weeks. Do you think this has anything to do with my nausea. I am also recently getting pains up my left leg and in my two feet rspecially at night time. Is this all connected do you think?
