<s>[INST] I have terrible leg cramps at night, I have tried many suggested remedies....vinegar and honey, magnesium tables, TENS machine, topical ointments...the muscles in the right leg are in painful knots;the left leg has developed light tics. The bicep muscle in my left arm has a knot that is painless. I have been in physical therepy twice a week for several weeks with little improvement. The pain lessons as the day goes on. The nighttime is miserable. What d o you think is going on????? [/INST] Hello, As mentioned you have tried everything for the cramps, let me mention in this way, that the cramps are due to the cellular level physiological abnormalities in the sodium channels and due to the disruption of the same the cramps aren't stopping and none of the therapies is working for longer. As you been trying to work with a physiotherapist for less duration, I will advise you to take the exercise seriously and workout with a graded plan. All the methods you tried are for symptomatic relief, but for long-run results, you have to put your efforts. Some of the cases seen by me in my experience of 12 years have responded for a longer duration of exercise in a graded manner. You don't need to be with a physiotherapist all the time. Just learn the exercise for some weeks and follow the same at home and again do physiotherapy for some weeks and again follow. Your self-involvement in this therapy of cramps will help the whole process to become stronger and long-lasting. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist </s>
