Hi SuperM. welcome to NeuroTalks t.n forum

I am sorry you are dealing with this on both side

Bi lat. T.N.
Can I ask what type of Doctor you are seeing? Do you see a neuro doc? or a pain Doc? There is nerve blocks and other options also...
There are many types of meds for controlling this Most of us have been on or are still on that merry-go-round of trying one or another or a combo of meds until what works is found.
I am allergic to anti seizure meds . So I know how it is .
Dont give up . I think what Wizabeth said is right about the time limit of not covering pre existing cond.
I too hope you find the right option and get control over this very soon.
sending low pain wishes and positive energy to you.
PEACE
BMW
