Hello, I am seeking information for my mom. She is 64 years young and has diabetes. Her height is 5 foot and she weighs approx. 140 lbs. She was recently hospitalized with an infection of some sort in her kidneys and the doctors placed her on an IV with alternating antibiotics. Since that time, she has been experiencing a burning through out her body yet she is always cold. What could these symptoms possibly be contributed to? The doctor's told her to drink plenty of water to flush her system. Thank you for your advice.
