MG Exacerbation after Antibiotics?

Hi everyone! Has anyone had an MG exacerbation after a course of antibiotics? If so, how long has it lasted? And what antibiotics were to blame? I have been in remission for years without medication but currently experiencing a mild exacerbation after dealing with a bad case of strep and a strong course of antibiotics (penicillin didn't work so then went on high-dose cephalosporin in this case). I have been off of the antibiotics for about a week now but the MG symptoms are still there. I have seen the charts that have been published of antibiotics to avoid and have had success in avoiding the more MG-problematic medications. All the literature says that cephalosporin hasn't shown to cause exacerbations, and I have dealt with many different illnesses and used many different types of antibiotics without issue over the years so just wanted to see what people's experiences have been while I am awaiting a neuro appointment. Thanks in advance for any insights!
