my daughter who is now 5 years old experienced paralysis after getting into a jacuzzi and getting scared by the water level which came upto her neck. This paralysis attack lasted for few hours after which she was ok. Thereafter, she got a series of such attacks and everytime there was an anxiety that triggered it (when she was injected a medicine, taken for blood tests). This lasted about 3 weeks during which she got 6 of such attacks which would last anywhere between 1/2 hour to 24 hours. Her recovery would happen in an instant. Nothing conclusive came out of her tests (thyroid, cholesterol, phosphate cardiac echo, MRI all were normal). We were supposed to get EEG, CPK, Serum lactate and B12 tests done for her but decided to wait for sometime since she would get an attack everytime she got a blood test. It has now been over 2 months since she's had her last paralytic attack. However, i noticed a grey hair on her which i know wasn't there earlier. I know Vit B12 can cause greying and it can also cause paralysis. Please advice...
