I am 56 and female. Have experienced past 5 years of anemia that was very critical. Constant weakness and bleeding. For the past 6 months no cycle except one day recently with one period of clot loss. Nerves have been on edge and took Tylenol for a couple of years for back pain. Have curvature of the spine and dislocated pelvic bone on right side. Lately am experiencing constant fluttering in legs, thighs, feet and even in head and sometimes in ears. WHAT may be wrong with me? I also occasionally take an antidepressant. Perhaps one every three weeks or so.
