Potassium or iron deficiency??
I am a 115lb 5ft5 female, recently lost 20 pounds. I eat about 1700-2000 cals a day. I have a very active workout schedule, but about a month ago, and a few times since then, I have woken up in the middle of the night with excruciating pain in my calves. It hurts tremendously, then it it just sore the whole day. Am I lacking in potassium or iron? Or what can be the cause of this? Please help
