First, I don't think the antibiotic was given to your friend to "remove" the cyst, it was probably given to help with an infection
caused by the cyst. infection
s can cause some of us with MS to have flares or MS symptoms b/c our body's immune system is reacting to the infection
(MS involves our immune system attacking our central nervous system). So it's possible her infection
is really what caused her symptoms to occur.
