I am really tired all the time even if I had 10 hours sleep, I am really thirsty too. so much I finish off a large jug during the day when I usually never needed to drink this much. I also get really red in the face after walking up a flight of stairs. I am 24,, female, I have asthma but never this bad and I exercise regularly. I am thin as well 115lbs and I dont know if relevant but I had a son three years ago. After my sons birth I had a IUD put in and I went it for it to get checked as my lower back had intense pains on the side, I thought it was my IUD making a pregnancy my doctor wanted to rule out appendicitis . So I did tests but no results yet, but im still so tired and thirsty and get cramps . What could it be and what should I do?
