Ultrasound: NORMAL! Thank you Jesus.
Blood Tests....NOT NORMAL. My iron is EXTREMELY low and my Vitamin D is a little low. Hmmm....I am off to the store today to get my supplements.
And then I found this online:
"Iron Deficiency in Runners Can Reduce Their Performance
Not only does iron deficiency cause fatigue, it reduces running performance. Iron has the critical job of supplying cells with oxygen, and if muscle cells don't have enough oxygen during exercise, they produce lactic acid. When lactic acid builds up, it causes muscle fatigue, which isn't a good thing if you're a runner. One study showed runners who supplemented with 100 milligrams of ferrous sulfate for six weeks, had better endurance and less muscle fatigue even if they didn't have low iron levels."
Hmmmm...have we found our answer?
I will let you know.
