Dear Karen, From the description of your symptoms, it sounds as if you may be having muscle cramps. Cramps usually occur during the night, after a day of strenous activity, and less often during the day. The can occur during a period of relaxation or after a strong contraction. Cramps are known to increase in frequency under certain conditions and with certain diseases. Dehydration and excercise may cause electrolyte abnormalities that predispose patients to cramps.
Cramps can also occur with low thyroid states and with certain muscle diseases.
I recommend getting an evaluation that includes a good physical exam and routine labs and thyroid test.
