RLS Hail Mary

My RLS has progressed such that even with meds (Gabapentin, Ropinirole, Vitamin B12, Iron) I have “attacks” where it is so bad it keeps me awake for literally days at a time because I am unable to sit or lay down for even a couple of minutes. Both of my legs cramp from my ankles, to my calfs and quads. It is excruciating pain and I become delirious from standing, walking, flexing, stretching and moving non-stop for two, sometimes three days until I end up basically collapsing from exhaustion. I have gone to the ER but they do nothing, not even admit me. I just can’t keep going like this and wonder if it is something more than RLS, but all of the doctors, neurologists, sleep study people and psychiatrists all just keep pointing me to the same solutions that clearly don’t work.

Please any insights, advice or if anyone has similar symptoms with alternate diagnoses and remedies please help.

Thank you.
