permanent calf cramps

hi doctor,
pls help me i am suffering from calf stiffness,pain,big size (as compared to body),some one told to excercise such as skipping but when i performed  my calf turened out more stiff,tight,big size even after one minute of skipping i felt i skipped for an hour. I used to drink 7-8 litre of water every day. Stiffness is much more in deep viens. My cpk nac test for heart is good,my skin & hair are good so no hypothyroid. Problem increases whenever  i am under stress.
I am suffring this problem for last 12 years its like permanent cramps in calf muscle.i can not perform any heavy excercise with my calf.I am NOT suffering from diabeties,heart problem,wht 75kg height 5.10". some time massage gives me some relax.i did every thing like streching,applying ice,some time applying heat, drinking fluids ,biggest problem is that
even i did not excercise for three years but problem is  same,is this related to
glycogen storage disease (GSD) or something else.Excercise has very little effect on my cramps.All my other body parts are athletic.

size of my nuscle is not normal its nearly 80% of my thigh.Even one dr said to me about this. pls help me little more.

Hi, here is some quoted literature “There are six basic causes of cramping: hyperflexion; inadequate oxygenation; exposure to large changes in temperature; dehydration; low blood salt; or low blood calcium. Muscle cramps may also be a symptom/complication of pregnancy, kidney disease, thyroid disease, hypokalemia or hypocalcemia (as conditions), restless legs syndrome, and multiple sclerosis.[1]
Electrolyte disturbance may cause cramping and tetany of muscles, particularly hypokalaemia (a low level of potassium) and hypocalcaemia (a low level of calcium). This disturbance arises as the body loses large amounts of interstitial fluid through sweat. This interstitial fluid is composed mostly of water and table salt (NaCl). The loss of osmotically active particles outside muscle cells(NaCl) leads to a disturbance of the osmotic balance and swelling of muscle cells as these contain more osmotically active particles. This causes the calcium pump between the muscle lumen and sarcoplasmic reticulum to short circuit and the calcium ions remain bound to the tropomyosin and the muscle contraction is continued. This may occur when the lactic acid is high in the cells”.
