why is it that i feel weak almost every day from 12 a.m till like 3-4 p.m, shaky, I feel like I am going to collapse to the ground, and my heart starts beating really fast? I read it might be a kidney infection; and the truth is about a week ago i had yellow, cheesy like discharge . I am very worried I hope i didnt disgust you and hope you can answer me. Thank you, I appreciate it god bless you. Regards, Ariadna Leon
