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
