Can I Take Pantoprazole For Nausea, Headache, Pain Outside Breast And Abdomen?

I have been experiencing nausea for the past week. Some periods of headaches. The outside of my breast gets this weird shooting mild pain and I have the same thing in my lower abdomen. I had a mild yeast infection that got treated with the one time pill. But it came back... although I never had discharge it was only red and swollen and sore and itchy. Now it is the same but pretty mild. I have a hard time to eat and I have experienced tunnel vision dizziness and lightheaded. I have seen two doctor since ... they checked my vitals and all was good. I had a pregnancy test that was negative my last period was heavier than normal from nov 25 th to 28th with one weird jelly think on day 3 of my period.... I got treated for H. Pylori last spring and never got tested after treatment so the doctor I saw yesterday gave me some pantoprazole to take .... Right now I am only experiencing the lil pains in my breast neck and lower abdomen and I have a pretty bad nausea .. no vomitting... I just want to have a second opinion ... the doctor I have seen are rushing me out without any advice
