I had the facial/ear tingling so bad when I first had Mirena out that it was painful. I even had shooting pains in my head during certain times. The Dr. had me so convinced that my problems were not Mirena related that I actually started to think that I had something else very wrong with me. Acupuncture and the chinese herbs given to me from the natural doctor took it away almost immediately. I have had a little minor tingling here and there but nothing like it was during the first month after removal.
I just had my third session of acupuncture specifically for brain fog, my biggest symptom left. I had it on Friday and couldn't believe how clear I was yesterday...on Mother's Day. Even my vision was more clear. I am very tired today because my little daughter had the flu last night so it is hard to tell today. I even had that elated feeling that I am going to get over this.
I am not a Dr. but if you go to some of the menopausal sites, there are comments all over from women getting tingling down their face and extremities. I think it is hormone based. I am sure your body had to readjust hormones again after having the supplemented hormone removed.
