hi! I am 23 years old woman in normal shape (height 164cm and weight 53kg) and I have quite healthy lifestyle. I have recently experienced dizziness, nausea and shortness of breath.Dizziness was so bad 2 days ago that I couldn’t stand up over 2-3min. Also I have been feeling tired for few months. Even after 12 hours of sleep I don’t feel like I’m rested. I have trouble with concentration. I have experienced night sweats which I haven’t experienced before as I mostly feel cold not warm. Usually my hands and feet are cold which I have thought is because of bad circulation. I have had headaches about once a week for few months. Only medication I take is contraception pills and occasionally vitamin D and B. This situation has disturbed my everyday activities and working and I Would appreciate to get some advice how to solve it. Thank you!
