cramp inner thigh muscle?

my mother has been suffering cramp in her top inner thigh.muscle. it only happens in the one musscle and she can feel the cramp comming on a couple of days prevous to it happening . she has tried taking crampex which is an over the counter product but this does not seem to help. she is Medication for Diabetes and mild Blood pressure i have read the side effect and none seem to state this. the doctor has said it is just cramp. but i wonder if anyone has any suggestions of how to get tests done on maybe minreral or Nutrient Deficiency - or has any suggestions - she says the pain is worse than Childbirth !
she has tried Eating 2 bananas a day to help with potasium.
I have similar problems (type 2 diabetic, high BP and cramp). I found that increasing the amount of walking I did helped more than anything else. I also drink a large glass of Tonic water before bed (it contains quinine which is good for cramp)...fingers crossed, it has worked pretty well for me;
