Me and my siblings don’t know what to do. Our 70 yr old father's health is deteriorating before our eyes. What started out a few years ago as just numbness in his right leg, and “ dropped foot” (can’t pick up foot) he constantly falls. He blew it off as a pinched nerve in his neck. Now, he is incontinent, hands are almost incapacitated, can’t grip, looks clinched, extremely thin, hardly can walk without assistance, always cold, can keep his head dropped for hours, like tripod position, and refuses medical treatment. His speech is fine, memory is good. He denies pain, and says just numb. We feel we are neglecting this by his defiance. Since not having a PCP, and no diagnosis, can we take him to an ER ? We are desperate. Please advise ..
