You must be suffering from Electrolyte disorders.From the symptoms it seems to be due to lack of Calcium electrolyte in your body causing Neuromuscular excitability.
Hence i sincerely request you to do the following tests
(1)Complete blood count
(2)Serum electrolytes level (particularly S.Na,S.K,S.Ca,S.Mg).
If this is the case then you will have to get the disorder corrected immediately as it may worsen and may even become life threatening.
First do the investigations done and accordingly get the treatment started.
