Based on details you have hypokalemic periodic paralysis
with positive family history .This indicates primary hypokalemic periodic paralysis ( gene defect for channels located at skeltal muscle) rather than secondary causes .
Still you need detail evaluation like calcium, magnesium levels in blood,thyroid profile and Arterial blood
gases and assessment of kidney function in addition to serum potassium.You require specific tests like CPK and EMG also
Hypokalemc paralysis worsens with high carbohydrate
diet and heavy exercises.
Yes you can go ahead for surgery after correction of potassium and you may require acetazolamide
also. Discuss with treating neurologist
regarding aforementioned pal.
I hope this will help you
