I had to reply to your post. I KNOW EXACTLY what you are feeling. Your post sounds exactly like mine in the beginning. I started with chest pain, tingling in my legs and heavyness like i was walking through water. Muscle twitching the whole works. I was scared to death. I just have to let you know that I am know 2 years post removal and I am almost back to normal. It has been a very scary difficult road but I want you to know there is an end. You will get better. I still dont understand how the IUD could have caused such weird side effects and how they could have lasted so long after taking it out but I KNOW that the IUD caused it. I met a good friend 2 years ago on this side because we were experiencing the same symptoms and we were both scared and had no answers from the doctors. She is from Australia and I am from Alaska. But I couldnt have gotten through this without her. My left side was the worst, with weakness, heavyness and muscle twitching. I was so scared I had ALS. I am feeling SO much better now and I thought for a awhile there that I never would. It might help to go back and read some of my past postings. I you want to email me my email is email@example.com. I hope this gives you some comfort!
