I am 23 I have a 4yr old and 6 month old boys and for the past 5 or so months I have been getting light headed, dizzy, near to fully fainting, I continously feel tired and I yawn all day and from the time I wake up to the time I go to bed my legs hurt constantly and I feel I can not support my own weight. I have tried better foods in my diet, multivitamins, I have been on Ibprofan for the past 3 weeks for the leg pain, I go to bed early to get more sleep. I do not know why I am having these problems or how to treat them, any suggestions. I do have an appointment with my Dr. in a couple weeks but would like some suggestions for this.
