What causes extreme hand cramps and occasional leg cramps?
Thanks for the query.
I have read your query and understand your problem and concern.
Although lack of potassium and dehydration are very common causes for spasms in hand,there are various other reasons for such types of spasms like...
Lack of calcium and magnesium
Lack of VIT D
Use of diuretics leading to electrolyte loss
Chronic kidney conditions
Uncontrolled thyroid status
You need to consult your doctor and get investigated for above mentioned causes.
Once cause is found,it will be easy to treat you.
I hope it helps,however you are most welcome to revert to me for any further query.
Best of luck
