Psychiatric meds makes them worse, especially SSRIs. I tried
Neurontin and had success until week 2 when my jerks got stronger so I quit. I feel so left out with this and afraid to get worse. I had one period of a few months when they went away but came back.
Other symptoms: Agonizing restlessness, sometimes tremor, stiffness in arms, internal vibrations in left leg that comes and goes (sometimes non existent for a few months), fatique, severe brain fog and so on.
