Around Christmas time I started have shooting pains in my
left arm. It would extend to my shoulder, lower back and even down to my legs. I also have heart palpitations but the cardiologist said my heart is just fine and that they are caused my thyroid issues. Anyway, since then I get cramps, tingling, cold feelings, dull pains and such on the left side of my body, mostly in the arm and shoulder area and sometimes my heart. I get headaches on that side too.
