That´s certainly an interesting question!
I´m interested in myasthenia that might be pregnancy related......

I´ve had exactly the same Lawgirl. Do you know the reason why the reaction takes so long?
I was looking around and the only thing I found about medication and delayed presentation of myasthenic symptoms was this:
"Myasthenia gravis exacerbations developed a median of 1 day following fluoroquinolone exposure. The 37 cases describe dyspnoea (n = 19; 51%), myasthenic crisis requiring ventilatory support (n = 11; 30%) and death (n = 2; 5%). Additional exacerbation-related adverse events were generalized muscle weakness (n = 20; 54%), dysphagia (n = 9; 24%), diplopia (n = 6; 16%) and ptosis (n = 6; 16%). Six patients (16%) experienced a positive rechallenge, with recurrent myasthenia gravis exacerbation after fluoroquinolone reintroduction."

Good luck with that operation - Hope your doctor can figure this out - at least have someone monitoring you/people with you the day after.
