The weird buzzing and electrical sensations went away for me after the 2nd period at around 2 months post-removal. Occasionally, right before my period starts, I can feel the slightest sensation in my left foot. But, it's hardly noticeable and doesn't last very long, so it doesn't bother me too much. I can understand why you are concerned about this. That was one of the side effects that really freaked me out. How many periods have you had since removal? Are they back to normal? Have you noticed a trend as to when you have these sensations...right before your period or around ovulation? I am convinced that we all have one stubborn side effect that lingers until our hormones are completely balanced. For me, it's anxiety. I have that right now as a matter of fact because I'm on day 9 of my cycle and probably ovulating. Maybe this is your lingering side effect (unfortunately). How is the joint pain and weakness? Has it gotten better?
