All day today, I have had sharp pain in my right foot on and off. The last few days I have had pain in the lower abdomen and lower back. Could these pains be related somehow? I have also been feeling nauseous now and then throughout the days, mostly in the evening after 4pm. I have an appointment with doctor for next(only time I could get) but wanted to know if anyone had any opinions or suggestions about these symptoms. Please help.
