Suggest Treatment End Stage Of Renal Failure And Orthostatic

My husband is a 55 year old male, with end stage renal failure. CHF and orthostatic b/ps. He s also diabetic. He fell a week ago Sunday , hitting his head. His movement behavior has become erratic and unstable, with head bobbling, arm movements as if fluffing something off him. Inability to sit, stand or lie down for any length of time. Severe leg movements. Hugging himself or poking. It s not conducive with subdural hemotoma. The meds he takes would not cause this to happen. Chlonodine, amlodipine, protein packs. Frosrenal, lasics, and insulin pen. He only takes mitodrine, or minoxidil as needed. For high or fall in b/ps. He s had pain management meds, but they re use is sporadic. It s been several months.
