I was on 3600mg per day gabapentin. Still had some nerve pain in shoulder. Doctor weaned me off this onto pregabalin. Having some awful symptoms now, even though I'm on 250mg x2 per day and told to increase by 50mg every 2 weeks upto max of 300 x2 per day. She says if pregabalin doesn't work then she'll wind me back slowly to restart gabapentin. All seems trial and error. But I'm struggling with it. Does anyone know of alternatives. I have thalamic pain syndrome. Thanks
