For the past few months I've been experiencing hypothyroidism symptoms: chronic fatigue, hair loss, joint pain, constant coldness, memory loss/foggy-ness, lack of concentration, irritability, heavier menstration, constipation. The symptoms hav worsened the past 3 weeks. I especially feel exhausted all the time, no matter how much sleep I get. My mother was diagnosed with hypothyroidism 2 years ago.
