Hello- I have recently noticed a tingly feeling in my feet- always having a cold feeling. I also have had some head fogginess. I recently went off birthcontrol in preparation for a laparoscopy (possibly endometriosis which looked like it has attached my ovary to my abdomen wall) and they will be putting in a IUD to help stop my heavy periods. I am wondering if it sounds like I may have low iron (due to the long and heavy cycles) or a reaction from coming off the birth control. I go next week for blood work for the surgery so I don t want to call again with another problem when I will be getting my blood checked in a few days? Any thoughts?
