Yes, miriam, I have had these symptoms of numbness and tingling for years, on and off. I have found that taking magnesium helps. Also, I have had the hoarse voice. That was due to hypothyroidism. I take medication for that now. Just this morning, I read a naturopath on the topic of iodine - saying that we don't get enough. I have heard otherwise. He says that not enough iodine leads to hypothyroidism. He says that even if you have autoimmune hypothyroidism it is good to take iodine. Other sources say no. I know this much. If I take Iodine, I feel better. You might want to check on this. Other symptoms of hypothyroidism: lethargy, weakness, sore joints, constipation, dry skin, wiped-out feeling, sometimes double vision, feeling cold, "brain fog" - memory problems, heavy periods, infertility, miscarriages, inability to lose weight - or weight gain with sensible eating, etc, etc, etc
