Dr. Manmeet Singh (General Practice) needs a second opinion on this medical case.
A 10 year old female child presents with stiffening of his arms and legs. Parents gave a history of weakness and tirdeness for 2 days.
She had 1 episode of vomiting today.
She has history of abdominal pain and lost 4 kg of weight in 3 months.
All her physical examination is normal except for biochemical test which shows hypokalemia, hypochloremia, and hyperbicarbonatemia. What could be the cause for this stiffness?
