Hello,
These symptoms can be due to hypothyroidism and without checking the thyroid hormone levels, one cannot say for sure. Symptoms of hypothyroidism are fatigue, depression,
weight gain, cold intolerance, dry, coarse hair and skin, constipation ,muscle cramps, decreased concentration, vague aches and pains, menstrual disorders, palpitation and swelling of the legs.
I feel that you should consult a physician and get yourself and your thyroid hormone levels evaluated.
