Hi there! I tested low in iron a few weeks ago, and have been carefully taking 3 pills a day for the past 3 weeks. I am very worried because the main symptoms (stiffness, cramping, coldness, and muscle loss in my legs) have barely gone away. I still cannot walk more than a couple blocks without having to sit and rest. I am 25 years old, 5'2", 115Lbs (gained about 5-10Lbs in the past while since I cannot move around). My iron levels are testing higher now, but I still don't feel like my old self. When can I expect to be well again? How long will it take?
