My sister had spinal tumor grade 1 non cancerous she underwent laminectomy as she was normal except the mild pain in her left leg but after surgery she got paralyzed. Now she's is taking treatment of gastric ulcers and getting normal, all reports are good except Hb which is 9.4 for this doctor transfused 2 unt of blood but now saying her to walk with support of physiotherapist without taking a MRI or giving blood thinner even doctor know that the patient is on bed rest from the last two months and have swelling feet, I am worrying about any risk, is it safe or not?
