First, I hope things get better and brighter for you! I've tried SO MANY medications...I'm on like 15 scripts now, give or take, which make it extremely hard to have a greater quality of life plus severe sleep deprivation due to pain and mental health issues.
I've tried oxcarbazepine (2) (150 mg) in the morning and at night but found that it wasn't helping as much as I expected plus it aided in my very low sodium level (which Neurologist) told me but PCP didn't know that and thought it's because of hydrochlorothiazide. Also, I have excruciating muscle spasms since starting oxcarb...so much so that I was recently admitted to the hospital *stayed 4 days. I've received steroids very IV (10x the amount that they give someone who is having an asthma attack for 4 days) and still not touching the muscle spasms. It even made my breathing labored when they come on (like contractions). I recently went back on Cymbalta (Duloxetine) at 60 mg per day. It's helping more than I expected but again still having muscle spasms. I suggest trying it. I've had Pregabalin and Gabapentin but they make me swollen. Perhaps, you could try one or both of those. Hope this helps!
