My mother is dealing with hypothyroidism since 2004. She is taking levothyroxine 125mg medicine daily. She has some feeling of numbness and pins and needles in whole body particularly near the chest and back. She also has some swelling around the breast area. She is taking additionally homeopathic medicine for this problem.but swelling is increasing and pain(pins and needles) is not decreasing.Is there anything to worry about some chronic heart disease or not. Please resolve this problem.
