Welcome to HealthcareMagic forum.
Yes, muscle cramps are associated with potassium deficiency
. Painful crams can occur if potassium and other electrolytes imbalance. Hope your doctor's have also ruled out inflammatory conditions. Serum creatinine
phosphokinase (CPK) can differentiate an ongoing muscle inflammation
from electrolyte imbalance
If the cause is only potassium deficiency, this could be attributed to some of your current medications especially the diuride and frusemide. Discuss with your treating doctor, perhaps reducing the dose or stopping these drugs should be considered.
Hope this answers your query.
