<s>[INST] I get severe muscle cramps in my rib cage. I can feel the muscle move and I can hardly stand it!!!!  I take vitamins, gatoraide, and drink water. When the cramps occur, I eat 2 Tbl of mustard, and drink water until it goes away --in about 5 min. I sometimes get them in my calf and thighs also. I started getting them about 20 years ago, and they are getting more frequent. [/INST] HI, I Did review your problemYour muscle cramps can be due to multiple reasons. I would advise you to get evaluated by a neurologist for any muscle related problem. Sometimes enzyme deficiencies and occasionally electrolyte defects can cause such problems. There are tests available to rule out and diagnose these problems and also treatment available for some. You can Chat Doctor. I hope this yellowish you a healthy life ahead </s>
