My friend had IV antibiotics for about 10 days in the hospital for a UTI infection. He recovered and was released, but has trouble using the IV arm. His other arm is paralyzed from a previous stroke. The IV arm was robust before and now he cannot grasp things and moves his weak arm awkwardly. I took him back to the ER because we were afraid of compartment syndrome. The CT scan was negative and arm weakness was determined from de-conditioning with recommended occupational therapy for the arm.
What happened here and what’s going on?
