question: My mom is 82 and has frequent feelings of an electric shock or severe pin pricks on her arms and sometimes her hips. She has stage 4 kidney disease and is sometimes dehydrated. She also takes 3 high blood pressure medications and tramadyl frequently. Could the feelings she s having be caused by dehydration or her medication? She is also become paranoid and it seems like she is having hallucinations at night. Other than that she thinks very clearly. I would appreciate knowing what type of doctor to take my mom to see and what you think might be wrong.
