Hi Tete,
U're most welcome. Juz contributing abit. 1 jab normally last for about 4-6months. Do, in Dr. Chee's theory is tat, if we wanna prolong the effects (Means from 4-6mths to 1 yrs +++), it's strongly recommended tat we go for 2nd jab 1 mth from the 1st jab. I was told tat if the patient go for the 2nd jab within the month (+/- a few days), sometimes the effect might even be 'lifelong', coz the 2nd jab wil 'weaken' our jaw muscles before it get a chance to become 'strong' again.
Hmm, the procedure wise is if u're not afraid of pain kind, straightaway after consultation, Dr. will bring u to the Treatment rm to start the jabs liao. It's about 4 jabs per side. But, coz I'm quite the scarey-cat kind, so, Dr. gave me some numbing cream to apply, then I waiting for about 20mins before starting the jabs. But, anyway, I applied the cream at the wrong part, so, the pain of a few jabs given can be felt. Hmm, I can only describe the pain as better then having ur finger pricked when u gotta go for blood test. Another way to compare will be tat it's much less painful than BCG jab.
