Is this a problem from taking Iron???

My daughter is iron deficient and so takes 25 mg iron daily. If she tries to take it every other day, or even 5 out of 7 days, her iron and hemoglobin start dropping.

Are you sure it's the iron...sounds like you started a lot of new stuff at once. The following info mentions that it could be an electrolyte imbalance.

"It is not known exactly why muscle cramps develop. Insufficient stretching before exercise, exercising in the heat, and muscle fatigue may all play a role in their causation. Imbalances in the levels of electrolytes (sodium, potassium, chloride, calcium and phosphate) in the blood can also lead to muscle cramps."

Thanks guys...I'm not so sure it is muscular, but digestive tract cramping causing pains in the butt and groin area. I was thinking the iron was blocking me up more than normal for me and the stress was causing the pain. Or just the iron itself irritating the digestive lining--after all it is not used to getting iron!

njmom...thanks for the warning. I was pretty iron/B12 deficient and that was what put me into the supplements more...I was seeing stars just taking a shower and fainting pretty easily. I feel 100% better with more B12 and the iron so I don't want to mess that up
...this just hurts enough that walking and sitting are pretty uncomfortable and going potty is downright painful....lesser of two evils time.
